Stainless Steel 416 vs S42010
Stainless Steel · grade comparison
Stainless Steel 416 and S42010 are both stainless steel grades. S42010 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 20% for S42010, and S42010 is harder (225 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 fair).
416Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S42010Choose it when strength drives the design.
416 vs S42010: 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.

416 vs S42010 — frequently asked
Is S42010 stronger than 416?
Yes. S42010 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, 416 or S42010?
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, 416 or S42010?
416. Its machinability rates very good (80/100) against fair (45/100) for S42010.
