Stainless steel anti-rust ability ranking list

Also, the stainless steel we are talking about here is relative, not absolute. The strength of its corrosion resistance depends on the chemical composition of stainless steel itself and the type of environmental medium in which it is used.

For example, 304 stainless steel has excellent corrosion resistance in dry atmospheric environments. However, if it is used in coastal areas, the sea fog containing a large amount of salt in the atmosphere will quickly rust. 316 stainless steel will perform well under such conditions, so not any kind of stainless steel will not rust in any environment.

Stainless steel anti-rust ability ranking list

The fifth, 430 stainless steel, commonly known as stainless steel, has the worst corrosion resistance and is very easy to rust.

The Fourth, 201 stainless steel, most household stainless steel products are this type of stainless steel. Over time, almost all will rust.

The third, 304 stainless steel, the most economical and practical stainless steel, will not rust under normal use environments.

The second, 316 stainless steel, has strong anti-rust properties, but it is still unsatisfactory in high-concentration acid and alkali environments.

The first, 2205 duplex stainless steel, has super anti-rust ability even in harsh environments.
