Why does stainless steel wire mesh rust

Rusty reason
Stainless steel mesh products in different materials and environments will rust.
Such as material 201 stainless steel wire mesh products is no nickel stainless steel net, stainless steel wire in the chemical composition does not contain its a bit of nickel is 0 nickel, nickel is a kind of rare metal, it is not easy to rust in stainless steel wire, but in general conditions such as coastal cities, acid and alkali conditions using time in 6 months to 12 months will appear rust.
Will 304 stainless steel mesh rust? Should say will not rust, if use environment is in the high temperature, acid and alkali, coastal salt environment, in addition to the eight nickel content, but also a certain amount of carbon content, the higher content of carbon will make stainless steel wire mesh easy to rust, low content will not rust.
Usually material 304 carbon content in equal to or less than 0.06 will not rust, greater than 0.06 or 0.06, 0.08 will be easy to rust, salt fog test in our test 304 a low carbon content in the trial will not rust, soak in salt water 24 hours will not rust material of 304 l stainless steel wire mesh products will not rust, so the content of carbon is also one of the reasons affecting rust in stainless steel wire mesh products.
In 304 material in more than 316, 316L, 321 material won't appear rusty phenomenon, because of the high content of nickel, good carbon content is low generally content in equal to less than 0.03, excellent product quality of stainless steel wire mesh.
