Stainless Steel 154CM vs 416

Stainless Steel · grade comparison

Stainless Steel 154CM and 416 are both stainless steel grades. 154CM is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 275 MPa (39.9 ksi) for 416, about 64% more; tensile strength follows at 760 MPa (110 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 13% for 154CM, and 154CM is harder (235 HB vs 155 HB). 416 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 416 machines more easily (very good vs poor) and 416 sits in a lower cost tier (premium, $$$) than 154CM (high, $$$$).

154CMChoose it when strength drives the design.

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