How much do we know about the knowledge of stainless steel? There are many kinds of it, and the identification method is different. The following is a simple understanding of the identification method of stainless steel: 1, Austenitic stainless steel is marked with 200 and 300 series of numbers. 2. Ferrite and horses
For the knowledge of stainless steel, how much do we know about it? There are many kinds of it, and the marking method is different. The following is a simple understanding of the marking method of stainless steel:
1, Austenitic stainless steel with 200 and 300 series of digital marks.
2, ferrite and martensitic stainless steel with 400 series of digital marks. For example, some of the more common austenitic stainless steels are labeled 201, 304, 316, and 310.
3, ferritic stainless steel is 430 and 446 as the mark, martensitic stainless steel is 410, 420 and 440C as the mark, two-phase (austenite-ferrite).
4, stainless steel, precipitation-hardened stainless steel and high alloys with an iron content of less than 50% are usually named by patent names or trademarks.
