Stainless Steel 1.4029 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4029 and 416 are both stainless steel grades. 1.4029 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 740 MPa (107 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 15% for 1.4029, and 1.4029 is harder (215 HB vs 155 HB). 1.4029 is stiffer (215 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 good), 416 welds better (poor vs not recommended), and 1.4029 sits in a lower cost tier (standard, $$) than 416 (premium, $$$).

1.4029Choose 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.
