Stainless Steel 1.4482 vs 2101
Stainless Steel · grade comparison
Stainless Steel 1.4482 and 2101 are both stainless steel grades. 1.4482 is the stronger of the two: yield strength 560 MPa (81.2 ksi) against 530 MPa (76.9 ksi) for 2101, about 6% more. In exchange, 2101 is the more ductile: elongation 38% versus 28% for 1.4482. 2101 runs hotter in service (300°C vs 250°C continuous) and 2101 conducts electricity better (2.7 % IACS vs 2.2 % IACS). On the shop floor, 1.4482 sits in a lower cost tier (standard, $$) than 2101 (premium, $$$).
1.4482Choose it when strength drives the design, or when cost is the deciding factor.
2101Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
1.4482 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.
