Stainless Steel 1.4423 vs 410
Stainless Steel · grade comparison
Stainless Steel 1.4423 and 410 are both stainless steel grades. 1.4423 is the stronger of the two: yield strength 780 MPa (113 ksi) against 310 MPa (45 ksi) for 410, about 152% more; tensile strength follows at 950 MPa (138 ksi) vs 517 MPa (75 ksi). In exchange, 410 is the more ductile: elongation 25% versus 16% for 1.4423, and 1.4423 is harder (300 HB vs 155 HB). 410 runs hotter in service (650°C vs 300°C continuous) and 410 conducts heat better (24.9 W/m·K vs 16 W/m·K). On the shop floor, 410 machines more easily (good vs fair), 1.4423 welds better (very good vs fair), and 410 sits in a lower cost tier (premium, $$$) than 1.4423 (high, $$$$).
1.4423Choose it when strength drives the design, or when it will be welded.
410Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4423 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.
