We should pay attention to check the requirements of the stainless steel sheet on corrosion resistance, which mainly depends on its alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal organizational structure, the main role is the chrome. Chromium in wuxi stainless steel sheet has high chemical stability, after a specified retention time after discharge test force, it can form a passivation film on the surface of the steel. Stainless steel sheet in the passivation film calculation formula, you should pay attention to your own will will make the metal isolated from the outside world, protect the steel sheet does not rust. After the passivation film is destroyed, this corrosion resistance decreases. The chromium content of stainless steel sheet (%) is 17.00-19.00, the cutting length is one meter blank. Nickel content.%) 8.00-10.00, this stainless steel is a kind of universal stainless steel material, the oxidation resistance is better than 200 series of stainless steel material, high temperature resistance is also better.
Stainless steel sheet has good corrosion resistance and good resistance to intergranular corrosion. In sampling, for the oxidizing acid, such as that used to support the pressure of the liquid, in the experiment: concentration Less than or equal to 65% of the boiling temperature of nitric acid, stainless steel has strong corrosion resistance . It also has good corrosion resistance to alkali solution and most organic and inorganic acids.
The installation conditions of stainless steel sheet, we must pay attention to the implementation of the standard, the surface is beautiful and the possibility of diversified direct materials, corrosion resistance is good, durable range than ordinary steel, strength It is also very tall. When stainless steel sheet is actually used, it can resist the quality of fire, using normal temperature processing, that is, easy transformation of plastic processing, because there is no surface treatment, so it is simple and simple maintenance.
