Stainless Steel 1.4122 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4122 and 416 are both stainless steel grades. 1.4122 is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 275 MPa (39.9 ksi) for 416, about 67% more; tensile strength follows at 780 MPa (113 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 18% for 1.4122, and 1.4122 is harder (240 HB vs 155 HB). 1.4122 is stiffer (216 GPa vs 200 GPa) and 416 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 416 machines more easily (very good vs fair).

1.4122Choose it when strength drives the design.

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