Stainless Steel 1.3549 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.3549 and 416 are both stainless steel grades. 1.3549 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 1.3549, and 1.3549 is harder (245 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 welds better (poor vs not recommended).

1.3549 vs 416 — frequently asked

Is 1.3549 stronger than 416?

Yes. 1.3549 has a typical yield strength of 450 MPa (65.3 ksi) against 275 MPa (39.9 ksi) for 416 — about 64% more. Tensile strength is 760 MPa (110 ksi) vs 515 MPa (74.7 ksi).

Which is cheaper, 1.3549 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, 1.3549 or 416?

416. Its machinability rates very good (80/100) against poor (30/100) for 1.3549; for welding the order is 416 first (poor, 22/100) then 1.3549 (not recommended, 10/100).
