Stainless Steel 1.4123 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4123 and 416 are both stainless steel grades. 1.4123 is the stronger of the two: yield strength 600 MPa (87 ksi) against 275 MPa (39.9 ksi) for 416, about 118% more; tensile strength follows at 880 MPa (128 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 14% for 1.4123, and 1.4123 is harder (255 HB vs 155 HB). 416 runs hotter in service (650°C vs 400°C continuous) and 416 conducts heat better (24.9 W/m·K vs 20 W/m·K). On the shop floor, 416 machines more easily (very good vs fair) and 416 sits in a lower cost tier (premium, $$$) than 1.4123 (high, $$$$).

1.4123Choose it when strength drives the design.

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