Stainless Steel 410 vs S41003
Stainless Steel · grade comparison
Stainless Steel 410 and S41003 are both stainless steel grades. S41003 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 310 MPa (45 ksi) for 410, about 13% more. S41003 is harder — 165 HB against 155 HB for 410 — which matters for wear surfaces and threads. S41003 conducts heat better (30 W/m·K vs 24.9 W/m·K). On the shop floor, S41003 welds better (very good vs fair) and S41003 sits in a lower cost tier (budget, $) than 410 (premium, $$$).
S41003Choose it when strength drives the design, or when surface hardness matters.
410 vs S41003: 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.
