Stainless Steel 1.4062 vs 2205
Stainless Steel · grade comparison
Stainless Steel 1.4062 and 2205 are both stainless steel grades. 2205 is the stronger of the two: tensile strength 790 MPa (115 ksi) against 750 MPa (109 ksi) for 1.4062, about 5% more. In exchange, 1.4062 is the more ductile: elongation 35% versus 30% for 2205, and 2205 is harder (255 HB vs 230 HB). 2205 runs hotter in service (300°C vs 250°C continuous). On the shop floor, 1.4062 sits in a lower cost tier (standard, $$) than 2205 (specialty, $$$$$).
1.4062Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
2205Choose it when strength drives the design, or when the part sees heat.
1.4062 vs 2205: 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.
