Stainless Steel 1.4057 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4057 and 416 are both stainless steel grades. 1.4057 is the stronger of the two: yield strength 680 MPa (98.6 ksi) against 275 MPa (39.9 ksi) for 416, about 147% more; tensile strength follows at 870 MPa (126 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 17% for 1.4057, and 1.4057 is harder (270 HB vs 155 HB). 1.4057 is stiffer (215 GPa vs 200 GPa) and 416 runs hotter in service (650°C vs 500°C continuous). On the shop floor, 416 machines more easily (very good vs fair) and 1.4057 sits in a lower cost tier (standard, $$) than 416 (premium, $$$).

1.4057Choose it when strength drives the design, or when cost is the deciding factor.

416Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
