What brands of stainless steel are there?

Stainless steel is usually divided into 20 1, 202, 30 1, 304, 309s, 3 10s, 4 10, 420, 43 1 etc. Among them, 20 1, 202, 30 1, 304, 309s and 3 10s belong to austenitic stainless steel, which contains no magnetism and can be corroded by various media. 4 10, 420, 43 1 are martensitic stainless steels with high magnetic properties and strength, but poor plasticity and weldability.

1. What is stainless steel?

Stainless steel is usually divided into martensite steel, ferrite steel, austenite steel, austenite-ferrite (duplex) stainless steel and precipitation hardening stainless steel. In addition, it can also be divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel.
