Stainless Steel 410 vs 7Cr17MoV
Stainless Steel · grade comparison
Stainless Steel 410 and 7Cr17MoV are both stainless steel grades. 7Cr17MoV is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 310 MPa (45 ksi) for 410, about 5.5 times as much; tensile strength follows at 1,950 MPa (283 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 4% for 7Cr17MoV, and 7Cr17MoV is harder (620 HV vs 160 HV). 410 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 410 machines more easily (good vs not recommended), 410 welds better (fair vs poor), and 7Cr17MoV sits in a lower cost tier (standard, $$) than 410 (premium, $$$).
410Choose 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.
410 vs 7Cr17MoV: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all stainless steel grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

410 vs 7Cr17MoV — frequently asked
Is 7Cr17MoV stronger than 410?
Yes. 7Cr17MoV has a typical yield strength of 1,700 MPa (247 ksi) against 310 MPa (45 ksi) for 410 — about 5.5 times as much. Tensile strength is 1,950 MPa (283 ksi) vs 517 MPa (75 ksi).
Which is cheaper, 410 or 7Cr17MoV?
7Cr17MoV is the lower-cost material: it sits in the standard tier ($$) while 410 is premium ($$$). 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, 410 or 7Cr17MoV?
410. Its machinability rates good (55/100) against not recommended (8/100) for 7Cr17MoV; for welding the order is 410 first (fair, 45/100) then 7Cr17MoV (poor, 15/100).
