Stainless Steel 1.4415 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4415 and 416 are both stainless steel grades. 1.4415 is the stronger of the two: yield strength 720 MPa (104 ksi) against 275 MPa (39.9 ksi) for 416, about 162% more; tensile strength follows at 900 MPa (131 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 17% for 1.4415, and 1.4415 is harder (285 HB vs 155 HB). 1.4415 is stiffer (215 GPa vs 200 GPa) and 416 runs hotter in service (650°C vs 450°C continuous). On the shop floor, 416 machines more easily (very good vs fair) and 1.4415 welds better (very good vs poor).

1.4415Choose 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.

1.4415 vs 416 — frequently asked

Is 1.4415 stronger than 416?

Yes. 1.4415 has a typical yield strength of 720 MPa (104 ksi) against 275 MPa (39.9 ksi) for 416 — about 162% more. Tensile strength is 900 MPa (131 ksi) vs 515 MPa (74.7 ksi).

Which is cheaper, 1.4415 or 416?

Both sit in the same relative cost tier ($$$, premium); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which is easier to machine, 1.4415 or 416?

416. Its machinability rates very good (80/100) against fair (35/100) for 1.4415; for welding the order is 1.4415 first (very good, 70/100) then 416 (poor, 22/100).
