Stainless Steel 410 vs S42030
Stainless Steel · grade comparison
Stainless Steel 410 and S42030 are both stainless steel grades. S42030 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for 410, about 23% more; tensile strength follows at 690 MPa (100 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 22% for S42030, and S42030 is harder (210 HB vs 155 HB). On the shop floor, 410 machines more easily (good vs fair), 410 welds better (fair vs poor), and S42030 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 is machined in volume.
S42030Choose it when strength drives the design, or when cost is the deciding factor.
410 vs S42030: 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 S42030 — frequently asked
Is S42030 stronger than 410?
Yes. S42030 has a typical yield strength of 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for 410 — about 23% more. Tensile strength is 690 MPa (100 ksi) vs 517 MPa (75 ksi).
Which is cheaper, 410 or S42030?
S42030 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 S42030?
410. Its machinability rates good (55/100) against fair (42/100) for S42030; for welding the order is 410 first (fair, 45/100) then S42030 (poor, 25/100).
