Stainless Steel 1.4462 vs 2101
Stainless Steel · grade comparison
Stainless Steel 1.4462 and 2101 are both stainless steel grades. Both yield at about 540 MPa — strength does not separate them. 2101 is the more ductile: elongation 38% versus 30% for 1.4462, and 1.4462 is harder (250 HB vs 230 HB). 2101 runs hotter in service (300°C vs 250°C continuous) and 2101 conducts electricity better (2.7 % IACS vs 2.2 % IACS).
2101Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4462 vs 2101: 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.
