Stainless Steel 1.4903 vs 416

Stainless Steel · grade comparison

Stainless Steel 1.4903 and 416 are both stainless steel grades. 1.4903 is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 275 MPa (39.9 ksi) for 416, about 78% more; tensile strength follows at 660 MPa (95.7 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 23% for 1.4903, and 1.4903 is harder (215 HB vs 155 HB). 1.4903 is stiffer (218 GPa vs 200 GPa). On the shop floor, 416 machines more easily (very good vs fair) and 1.4903 welds better (fair vs poor).

1.4903Choose 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 is machined in volume.

1.4903 vs 416 — frequently asked

Is 1.4903 stronger than 416?

Yes. 1.4903 has a typical yield strength of 490 MPa (71.1 ksi) against 275 MPa (39.9 ksi) for 416 — about 78% more. Tensile strength is 660 MPa (95.7 ksi) vs 515 MPa (74.7 ksi).

Which is cheaper, 1.4903 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, 1.4903 or 416?

416. Its machinability rates very good (80/100) against fair (38/100) for 1.4903; for welding the order is 1.4903 first (fair, 42/100) then 416 (poor, 22/100).
