How much do you know about the knowledge of stainless steel? There are many types of it, and the identification methods are also different. Here is a brief understanding of the identification methods of stainless steel:
1. Austenitic stainless steel is marked with 200 and 300 series numbers.
2. Ferritic and martensitic stainless steels are marked with 400 series numbers. For example, some of the more common austenitic stainless steels are marked with 201, 304, 316, and 310.
3. Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C, duplex (austenite-ferrite).
4. Stainless steel, precipitation hardening stainless steel and high alloys with iron content less than 50% are usually named by patent names or trademarks.
