Stainless Steel 2205 vs S32202
Stainless Steel · grade comparison
Stainless Steel 2205 and S32202 are both stainless steel grades. 2205 is the stronger of the two: tensile strength 790 MPa (115 ksi) against 750 MPa (109 ksi) for S32202, about 5% more. In exchange, S32202 is the more ductile: elongation 35% versus 30% for 2205, and 2205 is harder (26 HRC vs 23 HRC). On the shop floor, S32202 sits in a lower cost tier (premium, $$$) than 2205 (specialty, $$$$$).
2205Choose it when strength drives the design.
S32202Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
2205 vs S32202: 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.
