Stainless Steel S35125-AW vs S35125-CW
Stainless Steel · S35125 temper comparison
S35125-AW and S35125-CW are two conditions of the same stainless steel grade, S35125: AW (as-welded deposit) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. S35125-CW is the stronger of the two: yield strength 590 MPa (85.6 ksi) against 300 MPa (43.5 ksi) for S35125-AW, about 97% more; tensile strength follows at 800 MPa (116 ksi) vs 570 MPa (82.7 ksi). In exchange, S35125-AW is the more ductile: elongation 30% versus 20% for S35125-CW, and S35125-CW is harder (240 HB vs 180 HB). S35125-AW runs hotter in service (1,050°C vs 550°C continuous).
S35125-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S35125-CWChoose it when strength drives the design.
S35125-AW vs S35125-CW: 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.

S35125-AW vs S35125-CW — frequently asked
Is S35125-CW stronger than S35125-AW?
Yes. S35125-CW has a typical yield strength of 590 MPa (85.6 ksi) against 300 MPa (43.5 ksi) for S35125-AW — about 97% more. Tensile strength is 800 MPa (116 ksi) vs 570 MPa (82.7 ksi).
Which condition does FabDigit quote by default, AW or CW?
SA is the default S35125 condition in the FabDigit quote flow (neither AW nor CW). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, S35125-AW or S35125-CW?
S35125-AW. Its weldability rates good (65/100) against good (60/100) for S35125-CW.
