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.

Use the principle of 430 stainless sheet presentation

430 stainless sheet steel is to ask the entire root organizations are uniform in width and length. Bright annealing furnace muffle muffle the use of large size, organization from outside the muffle 430 stainless sheet uniformly heated airflow spiral surrounded by, uniform heating of the strip. And to ensure uniform along the length direction of the strip of tissue, 430 stainless sheet is necessary to maintain the linear velocity of the strip in the furnace constant. So, in front of modern vertical furnaces are equipped with bright heat treatment can be precision adjusted roller tension adjustment device. 430 stainless sheet steel import and export not only make stainless steel factory the heat rate of speed to meet the requirements, not live affect the amount of empty sets or full sets of sets, but also to establish and fine adjustment of the tension strip small strip plate according to circumstances, to meet the board type of request.

Analysis of 409 stainless steel plate market steel

409 stainless steel plate editing learned in the construction steel market, the price decline was relatively large, 409 stainless steel plate market price decline of 110 tons to 190 yuan. After the Lantern Festival, many businesses reflect poor delivery, the 409 stainless steel plate  turnover in the doldrums trend has not changed. Social inventory increased significantly, to bring certain psychological pressure to the merchant. Have to remind people, it is important to note that, after the rapid callback for more than a week, the construction steel market price cost price already approached, the next step will be to previous business price reduced. 321 stainless steel plate representative manufacturers a new round of ex factory price stainless steel plate  the "flat", coupled with the weather warming, construction site will be gradually increased, the demand will improve. 409 stainless steel plate editing relevant mechanism analysis that in mid February, the national average crude steel production exceeded 2000000 tons, this is the first time since October last year. One is the steel production and inventory pressure simultaneously; the downstream demand on the other hand, the steel industry is Stainless Steel Sheets  not optimistic. In the background of steel overcapacity, even if macroeconomic warmer, is not enough to improve the iron and steel industry from the fundamental operations. Estimation of steel, or by weak consolidation pattern.

Compared with the ferritic stainless steel sheet coil

High content of alloying elements , the price is relatively high, generally does not contain nickel ferrite .
stainless steel coils manufacturers - and human health
Stainless steel is then mixed with iron -chromium alloy made ​​of some other trace elements . Due to the good performance of its metal and corrosion -resistant than other metals , utensils made ​​of beautiful and durable. Therefore , more and more being used to make kitchen utensils, and gradually into the majority of families .
However , if the user lacks knowledge of the authorities concerned to use , improper use of stainless steel plate 304 in the same trace metals will slowly accumulate in the body , when it reaches a certain limit, it will harm human health .
