Stainless steel can be divided by its composition, give priority to with chromium chromium stainless steel and is given priority to with chromium, nickel chromium nickel stainless steel two kinds big. Industry commonly used stainless steel generally classified by metallographic organization, can be divided into the following five categories: Martensite stainless steel, chromium content 12% ~ 18%, 0.1% ~ 0.5% carbon content (1%) sometimes, common have 1 cr13, 2 cr13 and 3 cr13, 4 cr13, cr18 1 cr17ni2, 9, 9 cr18mov, 30 cr13mo, etc. Ferritic stainless steel, chromium content 12% ~ 30%, common have 0 cr13si4nbre cr17ti cr13, 0, 0, 1 cr17, 1 cr25ti cr17m02ti cr17ti, 1, 1, 1 cr28, etc. Austenitic stainless steel: complex content 12% ~ 25%, 7% ~ 20% nickel content (or more than 20%), 1 cr18ni9ti is the most typical representative, common and 00 cr18ni10, 00 cr23ni28m03cu3ti cr18ni18mo2cu2ti cr18ni12mo2ti cr18ni14mo2cu2, 0, 0, 0, 1 cr13mn9ni4 cr14mn14ni, 2, 1 cr18mn8ni5n, etc. Austenite ferritic stainless steel: similar to austenitic stainless steel, only contains a certain amount of ferrite in the organization, common have 0 cr17mn13mo2n cr18mn10ni5m03n cr21ni5ti cr21ni5ti, 1, 1, 0, 1 cr17mn9ni3m03cu2n, 1 cr18ni11si4alti Cr2bNi17M03CuSiN, etc. Precipitation hardening stainless steel, with high chromium, nickel and low carbon, common have 0 cr15ni7m02al cr17ni7al cr17ni4cu4nb, 0, 0, etc. After the first two categories for chromium stainless steel, three kinds of chromium nickel stainless steel. |
