Stainless Steel 2101 vs S82011
Stainless Steel · grade comparison
Stainless Steel 2101 and S82011 are both stainless steel grades. 2101 is the stronger of the two: tensile strength 750 MPa (109 ksi) against 700 MPa (102 ksi) for S82011, about 7% more. 2101 is the more ductile: elongation 38% versus 32% for S82011. 2101 conducts electricity better (2.7 % IACS vs 2.2 % IACS). On the shop floor, S82011 sits in a lower cost tier (standard, $$) than 2101 (premium, $$$).
2101Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
S82011Choose it when cost is the deciding factor.
2101 vs S82011: 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.
