Stainless Steel: or call tape, coils, coil width is called more, the hardness of the strip, there are many, ranging from tens to hundreds, Customers buy easy to determine what needs to hardness. . (8K mirror luminosity) web width uncertain, there are: 30mm.60mm.45mm.80mm.100mm.200mm etc. also sub-section according to customer requirements from a metallographic point of view, because the stainless steel contains chromium leaving the surface is. chromium thin film, the membrane separating oxygen from inside the steel corrosion invasive role. In order to ensure the yield strength of various types of stainless steel coil, the mechanical properties of tensile strength, elongation and hardness to meet the requirements, you must go through annealing, solution heat treatment, aging heat treatment before delivery, stainless steel coil. The corrosion resistance of stainless steel coil depends on its organizational structure alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and stainless steel coil inside, play a major role in the chromium. Chromium has a high chemical stability, can form a passive film on the steel surface, the metal with the outside world to isolate and protect steel from oxidation and increase the corrosion resistance of steel. After the destruction of the passive film, corrosion resistance on the decline. Stainless steel coil is widely used in chemical, food, pharmaceutical, paper, oil, nuclear and other industries, as well as construction, kitchen utensils, cutlery, vehicles, household appliances all kinds of parts.

Development and application and development trend of stainless steel products

Global magnetic stainless steel sheets production, about 76% belong to the 300 series, which the international nickel price fluctuations in the price of nickel chromium stainless steel is considerable. Between the past year, prices of raw materials nickel, nickel-chromium makes relatively substantial growth in steel costs, leading consumers to have to actively look for alternatives, some of the market has also been replaced by alternatives. In recent years, low chromium stainless steel and nickel-based stainless steel (such as 200 series) development gradually by the parties seriously. Looking to the future, the proportion of low-chromium-nickel stainless steel and consumption will have to increase.
200 series stainless steel (Cr-Mn-Ni system)
Serious shortage of nickel supply during World War II, the German first developed manganese - nitrogen instead of part of the nickel stainless steel. 1950s, the United States is also the raw material due to the shortage of nickel, after in-depth research, successfully developed a series of high-manganese austenitic stainless steel or 200 stainless steel. 200 Series commonly used steel comprising: AISI 201 (16% ~ 18% Cr, 5.5% ~ 7.5% Mn, 3.5% ~ 5.5% Ni, <0.25% N), 202,205 and Indian J1, J4 (containing Cu) other costs 25% lower than the 304 for the general purposes of weak corrosive environments such as utensils, kitchenware, interior decoration, etc., poor welding performance. Recently, the US developed 204Cu (3% Cu), compared with 304 stainless steel, high strength, cold performance is more excellent corrosion resistance and 304 rather, it is possible to replace 304 become widely used stainless steel variety.
400 series stainless steel
400 series traces the development trend of adding Nb, Ti, Cu, Al improving deep drawability, weldability, corrosion resistance, antimicrobial resistance and high temperature strength, etc., can be partially replaced by 304, the main steel grades: SUS430LX, 430JIL, 444 , 445M2, NSS 477M1 and so on. United States and Japan have been widely used in automotive exhaust pipe (409, 410), the washing machine drum (430), kitchenware, household appliances, medical equipment, water heaters, roofs, walls, plants and so on.

Advantages and disadvantages of the three stainless steel polishing methods

stainless steel plate 304 polishing methods are commonly used mechanical polishing, chemical polishing, electrochemical polishing are three of these three methods each have their own advantages and disadvantages.

1, the mechanical polishing.
The advantage is processed parts leveling good, high brightness. The disadvantage is labor-intensive, polluting, and complex parts can not be processed, and its luster is not consistent, gloss retention time is not long, nausea, rust. More suitable for processing simple pieces, medium and small products.
2, chemical polishing.
The advantage is less investment in processing equipment, complex parts can throw, high speed, high efficiency, good corrosion resistance. The disadvantage is that the brightness difference, a gas spill, require ventilation, heating difficulties. Suitable for processing small quantities of complex parts and small parts brightness less demanding products.
3, electrochemical polishing
The advantage is to maintain long specular gloss, process stability, low pollution, low cost, good corrosion resistance. The disadvantage is that pollution is high, a large one-time investment in processing equipment, complicated thing to tooling, auxiliary electrode, mass production facilities also need to cool down. Suitable for mass production, mainly used in high-end products, the export of products, there is a tolerance of products, which process is stable, easy to operate.

Stainless steel grinding instructions

stainless steel 304 csp parts to achieve surface quality and precision requirements, usually grinding methods. Due to the large stainless steel toughness, thermal conductivity, low elastic modulus, so there are problems in the grinding often:

1) easy to adhere to clog the wheel; 2) the machined surface is easy to burn;

3) hardening serious; 4) of the workpiece deformation.

Difficult to see, select and grinding wheel grinding fluid directly affects the efficiency and precision. This paper jam affecting adhesion and surface roughness factors were studied.


2 Experimental conditions and methods

Specimen material selection 1Gr18Ni9Ti, its mechanical properties: σb = 530MPa, σ = 40%, hardness HB = 187 specimen size diameter φ50mm, length 300mm, φ50 cylindrical surface of fine cars, both ends of the plane hit the center hole. Experiments on MGB1420 cylindrical grinder, grinding wheel for P400 × 40 × 203, cylindrical grinding grinding way, in order to improve the reliability of the test results, repeat the test, observe the average effect, eliminate the influence of random factors, while try to keep the grinding conditions are basically the same, by changing the wheel size, hardness, abrasives, grinding fluid replacement, grinding to examine the impact on the amount of grinding effect.


3 experimental results

3.1 wheel size affect adhesion rate

Selection of corundum, hardness K, respectively, for the four wheel size 36,46,60,80 number of specimens were cylindrical grinding, grinding length of 600mm, detection adhesion rate, the finer the grinding wheel, stick attached to the more serious, this is due to the presence of voids between the grains, the grinding chips can be stored in the voids; and finer grinding wheel, voids smaller chip space quickly lose the wheel, causing blockage.


3.2 Effect of the adhesion rate of wheel hardness

Selection of the abrasive is fused aluminum oxide, particle size 46, hardness was H, J, K, L grade wheel, the specimen grinding, grinding stroke 600mm, detection adhesion rate. The higher the hardness of the wheel, the more severe adhesion. This is due to the low hardness of the grinding wheel, abrasive grains in the grinding force, easy to fall off from the wheel surface, the formation of new chip space, easy to plug.


The impact on the adhesion rate of 3.3 abrasive

Commonly used abrasive wheel has two kinds of corundum and silicon carbide green, experiments show that the impact of the two abrasive adhesion rate, the difference is not big, green silicon carbide can reduce the sticking slightly because of the crisp and sharp.


3.4 Effect of the surface roughness of grinding fluid

Respectively, using the three liquid emulsion, an inorganic salt grinding fluid and oil-based grinding fluid, was added sulfur, chlorine and other extreme pressure additives, observed after processing of the workpiece surface roughness, the flow rate of the grinding liquid is 20L / min, the grinding stroke of 600mm, the experimental results shown in Table 3.

As can be seen, the surface tension, containing extreme pressure additives, surface quality obtained by grinding. Rational use of grinding liquid, can improve heat dissipation, the grinding liquid can grinding debris and abrasive shedding flush, while in the metal surface to form a film, a lubricant, reducing surface roughness.


3.5 The amount of influence on adhesion rate of grinding

Workpiece speed, feed rate and grinding depth has little effect on the process, can be seen from Table 2, changing the depth of grinding, has little effect on the adhesion rate.


4. Conclusion

1) Stainless steel factory grinding, reducing wheel adhesion blocking is an important factor to improve grinding efficiency, processing should always trim wheel, keep a sharp cutting edge.

2) stainless steel grinding wheel selection of good self-sharpening wheel is the main objective, generally used in low hardness of the wheel is good, but you can not select the hardness is too low, otherwise the grains did not blunt it off. J recommended use level.

3) To reduce the grinding wheel adhesion obstruction, should be used in coarse-grained wheel. When coarse granularity with the No. 36, 46, when the choice of 60 grit grinding.

4) When the grinding of stainless steel, the use of GC grinding wheel improves the grinding efficiency.

5) grinding fluid selection must take into account the role of lubrication and cleaning of two, adequate supply, the choice of the surface tension, the emulsion containing extreme pressure additives, a high surface quality.

6) Select the amount of grinding allowance can be determined based on.

7) during the experiment found that the wheel organization and binders have some influence on the grinding process of stainless steel, is currently restricted by experimental means, pending further study.

Stainless steel coil is one of the best building materials

Since the stainless steel coils have many desirable properties of construction materials with the required, it can be said that the metal is unique, and its continued development. To make use of stainless steel in the traditional better performance, has been the improvement of existing stainless steel 409‍  and, in order to meet the stringent requirements of advanced building applications, is developing new stainless steel. Due to continuous improvement of production efficiency, quality, continuous improvement, stainless steel has become one of the most cost-effective materials architects iron 1.4016 steel 2r‍  Stainless steel set performance, appearance and use of features in one, so the stainless steel will continue to be one of the best building materials in the world.

409 stainless steel design

Over 60 years, architects have been selected 409 stainless steel plate to build cost-effective permanent structures. Many of the existing buildings fully explained this choice is correct. Some are very ornamental in nature, such as New York 410 ss plate Chrysler Building. But in many other applications, the role of the stainless steel is not so dramatic, but it plays an important role in the aesthetics and performance of buildings. For example, due to the stainless steel is more abrasion resistance and dent resistance than other metal materials of the same thickness, so the construction of sidewalks in the turnover rate of the local population, which is the material of steel strip for designers. Stainless steel is used for the construction of new buildings and restoration of historic monuments of structural materials for more than 70 years. The early design is calculated in accordance with the basic principles. Today, the design specifications, such as the American Society of Civil Engineers standard ANSI/ASCE-8-90 "cold forming steel structure design" and NiDI published jointly with the Euro Inox "structural steel design manual" has simplified the long life, good building design integrity of the structural parts.

409 stainless steel repair and clean-up

And other materials exposed to the atmosphere as, 409 stainless steel plate is also dirty. The lecture will analyze the future maintenance and clean-up costs of the design factors. However, rainfall, there is also a correlation between artificial irrigation and dirty surfaces. Determine the effect of rainfall through the same lath directly on the atmosphere and on the covered areas. Human artificial washing stainless steel coils manufacturers is achieved by using six scrubbing sponge with soapy water to the right of each block is determined every slat. The results showed that, compared with the slats in place and covered the place not to be flushed through the rain wash and scrub the artificial surface and remove dust deposition on the surface of the magnetic stainless has a good effect. Has also been found, the processing status of the surface also affect the surface roughness of the smooth surface area slats slats better results. So wash interval is influenced by many factors, the main factor is the aesthetic standards required. Although many steel wall is only flushed when the windows, but, in general, for washing the external stainless twice a year.

Type 409 stainless steel plate of

"Stainless steel" is not merely the term refers to a stainless steel, but said more than one hundred kinds of industrial 409 stainless steel plate, stainless steel are developed each in stainless steel 304ba‍ specific fields of application with good performance. The key to success is to understand the purpose of the first, and then determine the correct steel. Further details can be found on stainless steel prepared by the NiDI "stainless steel guide" floppy disk. Fortunately, building construction and steel-related applications are usually only six of them. They contain 17 to 22% chromium, preferably of steel further contains nickel. Adding molybdenum can be stainless steel plate‍ improved atmospheric corrosion, especially resistant to corrosion in chloride-containing atmosphere. Experience has shown that the degree of corrosion of the atmosphere varies from region to region. For ease of explanation, proposed to be divided into four areas, namely: rural, urban, industrial areas and coastal areas. Country is essentially pollution-free zone. Low population density of the area, only non-polluting industries. Typical urban residential, commercial and light industrial areas, the region has a mild contamination, such as traffic pollution.

Some stainless steel roll mill is still the intention to pull up

Currently, some stainless steel coils factory still pull up intentions, but unfortunately weak downstream, most businesses to ship-based, price increases fatigue. Prices are still up, but had a significant increase in some areas, steel prices have started to steady, the key lies in the lack of effective coordination of transactions. For the steel city, different stages, there will always be some initial temporary factors, but the only stainless steel‍ is the fundamental supply and demand fundamentals placement. According to the latest market report, steel prices continued to rise in the previous stage and continuing consolidation after the show season with the effects of domestic structural tube steel market supply and demand back again on this fundamental placement into shock down the track. On the current situation, the overall weak market demand for steel, raw materials 430 stainles‍ and more firm, which formed on the market some support. But because of the snail opened low today, and the mentality of the current manufacturers generally are not optimistic on the outlook that the downtrend is still changing, operating more cautious, so comprehensive or expected short-term market prices showed a slight concussion.

Stainless steel coil current market prices

stainless steel coils factory movement is the fastest, especially small and medium sized steel enterprises have once read about the return of stainless steel 430ba‍  will be the overall production. So the idea of a business idea will be the majority of enterprises, thus releasing the steel production capacity to face excessive supply and demand increased, and this is still an important factor in rising steel prices discourage late. The first three quarters of stainless steel magnetic‍  the entire steel industry can be said to be caught up in the history of the biggest downturn since the steel mills, steel trading business spinous loss, steel prices fell more I saw, few rally at all. Experts believe that China mold net capacity utilization of China's major steel mills have been quick to recover from the previous 75% to less than 86%, the latter with the improvement of stainless steel coil market, this situation is likely to further increase the resumption of production.
