Stainless Steel 1.4122 vs 410
Stainless Steel · grade comparison
Stainless Steel 1.4122 and 410 are both stainless steel grades. 1.4122 is the stronger of the two: yield strength 460 MPa (66.7 ksi) against 310 MPa (45 ksi) for 410, about 48% more; tensile strength follows at 780 MPa (113 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 18% for 1.4122, and 1.4122 is harder (240 HB vs 155 HB). 1.4122 is stiffer (216 GPa vs 200 GPa) and 410 runs hotter in service (650°C vs 400°C continuous). On the shop floor, 410 machines more easily (good vs fair) and 410 welds better (fair vs poor).
1.4122Choose it when strength drives the design.
410Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4122 vs 410: 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.

1.4122 vs 410 — frequently asked
Is 1.4122 stronger than 410?
Yes. 1.4122 has a typical yield strength of 460 MPa (66.7 ksi) against 310 MPa (45 ksi) for 410 — about 48% more. Tensile strength is 780 MPa (113 ksi) vs 517 MPa (75 ksi).
Which is cheaper, 1.4122 or 410?
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, 1.4122 or 410?
410. Its machinability rates good (55/100) against fair (45/100) for 1.4122; for welding the order is 410 first (fair, 45/100) then 1.4122 (poor, 22/100).
