Stainless Steel 2101 As Welded vs 2101 Cold Worked
Stainless Steel · 2101 temper comparison
2101 As Welded and 2101 Cold Worked are two conditions of the same stainless steel grade, 2101: As Welded (as-welded deposit) versus Cold Worked. The chemistry is identical, so every difference below comes from the condition. 2101 Cold Worked is the stronger of the two: yield strength 800 MPa (116 ksi) against 520 MPa (75.4 ksi) for 2101 As Welded, about 54% more; tensile strength follows at 950 MPa (138 ksi) vs 730 MPa (106 ksi). In exchange, 2101 As Welded is the more ductile: elongation 25% versus 12% for 2101 Cold Worked, and 2101 Cold Worked is harder (310 HB vs 240 HB). 2101 As Welded runs hotter in service (300°C vs 250°C continuous). On the shop floor, 2101 As Welded welds better (very good vs good).
2101 As WeldedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
2101 Cold WorkedChoose it when strength drives the design.
2101 As Welded vs 2101 Cold Worked: 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.
