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