Stainless Steel 1.4423 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4423 and 416 are both stainless steel grades. 1.4423 is the stronger of the two: yield strength 780 MPa (113 ksi) against 275 MPa (39.9 ksi) for 416, about 184% more; tensile strength follows at 950 MPa (138 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 16% for 1.4423, and 1.4423 is harder (300 HB vs 155 HB). 416 runs hotter in service (650°C vs 300°C continuous) and 416 conducts heat better (24.9 W/m·K vs 16 W/m·K). On the shop floor, 416 machines more easily (very good vs fair), 1.4423 welds better (very good vs poor), and 416 sits in a lower cost tier (premium, $$$) than 1.4423 (high, $$$$).

1.4423Choose it when strength drives the design, or when it will be welded.

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