Stainless Steel 416 vs 7Cr17MoV

Stainless Steel · grade comparison

Stainless Steel 416 and 7Cr17MoV are both stainless steel grades. 7Cr17MoV is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 275 MPa (39.9 ksi) for 416, about 6.2 times as much; tensile strength follows at 1,950 MPa (283 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 is the more ductile: elongation 30% versus 4% for 7Cr17MoV. 416 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 416 machines more easily (very good vs not recommended) and 7Cr17MoV sits in a lower cost tier (standard, $$) than 416 (premium, $$$).

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

7Cr17MoVChoose it when strength drives the design, or when cost is the deciding factor.

416 vs 7Cr17MoV — frequently asked

Is 7Cr17MoV stronger than 416?

Yes. 7Cr17MoV has a typical yield strength of 1,700 MPa (247 ksi) against 275 MPa (39.9 ksi) for 416 — about 6.2 times as much. Tensile strength is 1,950 MPa (283 ksi) vs 515 MPa (74.7 ksi).

Which is cheaper, 416 or 7Cr17MoV?

7Cr17MoV is the lower-cost material: it sits in the standard tier ($$) while 416 is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, 416 or 7Cr17MoV?

416. Its machinability rates very good (80/100) against not recommended (8/100) for 7Cr17MoV; for welding the order is 416 first (poor, 22/100) then 7Cr17MoV (poor, 15/100).
