Stainless Steel 2205 vs S32205
Stainless Steel · grade comparison
Stainless Steel 2205 and S32205 are both stainless steel grades. Both yield at about 540 MPa — strength does not separate them. On the shop floor, 2205 forms better (good vs fair) and S32205 sits in a lower cost tier (premium, $$$) than 2205 (specialty, $$$$$).

2205 vs S32205: 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.
