Stainless Steel 1.4962 vs 304

Stainless Steel · grade comparison

Stainless Steel 1.4962 and 304 are both stainless steel grades. 1.4962 is the stronger of the two: yield strength 320 MPa (46.4 ksi) against 250 MPa (36.3 ksi) for 304, about 28% more; tensile strength follows at 700 MPa (102 ksi) vs 585 MPa (84.8 ksi). In exchange, 304 is the more ductile: elongation 55% versus 38% for 1.4962, and 1.4962 is harder (185 HB vs 150 HB). 304 runs hotter in service (870°C vs 700°C continuous) and 304 conducts electricity better (2.4 % IACS vs 2 % IACS). On the shop floor, 304 machines more easily (fair vs poor), 304 welds better (excellent vs good), and 304 sits in a lower cost tier (standard, $$) than 1.4962 (high, $$$$).

1.4962Choose it when strength drives the design.

304Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
