stainless steel sheet coil reduces the overall

Stainless steel reduces the overall corrosion resistance and resistance to localized corrosion ( including pitting , crevice corrosion ) , and qiyi 304 stainless steel coil to stress corrosion cracking . Stainless steel mesh surface cleaning , pickling and passivation , except to maximize corrosion resistance , as well as to prevent product contamination and get beautiful role . Stainless steel mesh surface of the container made ​​of composite steel and has a corrosion requirements of this provision shall be pickling passivation is used for filtration in terms of petrochemical , because these devices for direct contact with the corrosive medium occasions corrosion corrosion resistance from the guarantee , raised pickling passivation is necessary. To other industries, such as the purpose is not for corrosion , clean and beautiful only 430 stainless steel magnetic, and you do not need the use of stainless steel pickling passivation . But also need to weld stainless steel equipment pickling passivation , the passive film on stainless steel mesh repair improved anti-corrosion properties .

How to ensure that the stainless steel sheet coil mesh shaker is never rust

In the acid environment to ensure that no rust stainless steel mesh , we must first selection of high quality stainless steel wire, stainless steel wire mesh corrosion mainly nickel content , the higher the nickel content , the more resistant to corrosion. Divided into non-nickel qiyi stainless steel coils mesh , two nickel, nickel- 4 , 304,316,316 L and other materials , 316L highest corrosion resistance . Another stainless steel mesh shaker to ensure that no rust is formed because the surface of a passive film , it is more stable in the presence of an oxide form in nature . That different conditions by the use of stainless steel mesh , is not the same degree of oxidation , can be oxidized under certain circumstances , this phenomenon is often called etching . Therefore , stainless steel mesh is not never rust. Exposed to the corrosive environment of the metal surface occurs all electrochemical reactions or chemical reactions uniform corrosion. stainless steel sheet coil mesh shaker surface passivation film corrosion resistance among the weak parts, due to the self-excited reaction to form pitting reaction of holes, coupled with chloride ions close to the formation of highly corrosive solution , accelerated corrosion reaction speed. There are inter- shaker internal corrosion cracking, all of them, on the surface of the stainless steel mesh shaker damaging effects of passive film occurred . Therefore, stainless steel mesh surface must be regular cleaning and maintenance to keep its beautiful surface and prolong life. Must be taken when cleaning the surface of the stainless steel mesh surface scratch phenomenon does not occur , and avoid the use of bleaching components of the washing liquid abrasive , steel balls , grinding tools, to remove the washing solution , and then wash the surface with clean water at the end of washing.

A larger proportion of electricity stainless steel , Asia ex Japan closer to European levels than normal with less. 1999 , Japanese electronics industry ferritic martensitic steel consumption reached 28% , accounting for 12% austenite . China's production of microwave ovens , refrigerators, air conditioners , television is a competitive export products in the world , the domestic appliance industry is a big market potential of stainless steel coils applications. It is estimated that the next 5-10 years , China's home appliance industry, stainless steel demand will reach 10 million -15 million tons.
Industrial waste gas , waste and sewage treatment device requires the use of stainless steel. In the flue gas desulfurization process, in order to resist sulfur dioxide and chlorine ions, iron ions corrosion in the absorber , coolers , pumps , valves, flue, etc. need to use duplex stainless steel and high- grade austenitic stainless steel. Garbage incinerator , waste water treatment facilities are required high-performance stainless steel.

Stainless steel gas stove

It is one of the areas of the earliest applications of stainless steel . In architectural terms , at present, qiyi 304 stainless steel plate mainly used in high-rise building facades , coating the interior and exterior columns , handrails, floor , elevator siding, doors, windows, walls and other interior and exterior decoration and components . After surface treatment , coloring , coating the stainless steel plate, prone to fingerprints to solve the problems touch after that to further expand the scope of application of 430 stainless steel sheets . Japan has developed a variety of stainless steel roofing materials , such as corrosion resistance better high chromium ferritic and a variety of coated sheet . Sweden developed the super-clean brushed stainless steel surface , the French Ugine developed UGITOP surface of the plate , for the construction industry provides a new choice.

Rapidly stainless steel coils machining

When making a selection , it is important to determine whether there are factors that affect the use of the local environment of the scene . For example , stainless steel with a factory chimney at the bottom , near the air conditioning vent with a baffle near or scrap yard , non- general conditions exist.
Ductile, for formed products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than  stainless steel sheet coil.
304 with corrosion resistance , due to the relatively high carbon intensity and therefore better .
By adding a small amount of sulfur and phosphorus to more than stainless steel coils.
304 better temperature resistance .
After 304 , the second most widely used types of steel , mainly used in the food industry and surgical equipment , adding Mo to obtain a special corrosion-resistant structure. Than the 304 because it has better resistance to chloride corrosion and thus as "marine steel" to use . Usually used to fuel recovery . Stainless steel is usually in line with the application level . In addition to the added titanium elements to reduce the risk of material outside the weld corrosion properties similar to 304.

stainless steel sheet coil more corrosive

Usually refers to the coastal area of less than one mile from the beach . However, the depth of the qiyi stainless steel sheet coil may spread to the interior, especially on the island , the prevailing winds from the ocean , and the bad weather . For example , the UK climate is so, so the whole country belongs to the coastal zone. If the wind mixed with the ocean mist, especially due to evaporation caused by the deposition of salt concentration , coupled with little rain , no rain washed often , the condition of coastal areas is even more unfavorable . If there is , then industrial pollution , the greater the resistance .
Research United States, Britain , France, Italy, Sweden and Australia have been conducted to determine the impact of these regions on a variety of atmospheric corrosion resistance of stainless steel 301 .
