The Common Types of 430 Stainless Steel

Austenite

301, 302, 303, 303se, 304, 304L, 304N1, 304N2, 304LN, 305, 309S, 310S, 316, 316L, 316N, 316J1, 316J1L, 317, 317L, 317J1, 321 , 347 , XM7 , XM15J1 , 329J1


Ferrite

405, 430, 430F, 434, 447J1, 403


Martensite

410, 410L, 405, 416, 410J1, 420J1, 420J2, 420F, 431, 440A, 440B, 440C, 440F, 630, 631, 632


There is also a stainless steel, 201, 202, 203, 204, which contains low chromium and high manganese. (Chromium high energy increases corrosion resistance, manganese high can make materials non-magnetic) This stainless steel has poor corrosion resistance and is generally used for dry environment decoration.
