Stainless Steel S32001 Annealed vs S32001 CW-TR
Stainless Steel · S32001 temper comparison
S32001 Annealed and S32001 CW-TR are two conditions of the same stainless steel grade, S32001: Annealed versus CW-TR (cold Worked / temper rolled strip). The chemistry is identical, so every difference below comes from the condition. S32001 CW-TR is the stronger of the two: yield strength 720 MPa (104 ksi) against 520 MPa (75.4 ksi) for S32001 Annealed, about 38% more; tensile strength follows at 850 MPa (123 ksi) vs 690 MPa (100 ksi). In exchange, S32001 Annealed is the more ductile: elongation 32% versus 14% for S32001 CW-TR, and S32001 CW-TR is harder (285 HB vs 230 HB). S32001 Annealed runs hotter in service (300°C vs 250°C continuous). On the shop floor, S32001 Annealed welds better (very good vs good).
S32001 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
S32001 CW-TRChoose it when strength drives the design.
S32001 Annealed vs S32001 CW-TR: 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.

S32001 Annealed vs S32001 CW-TR — frequently asked
Is S32001 CW-TR stronger than S32001 Annealed?
Yes. S32001 CW-TR has a typical yield strength of 720 MPa (104 ksi) against 520 MPa (75.4 ksi) for S32001 Annealed — about 38% more. Tensile strength is 850 MPa (123 ksi) vs 690 MPa (100 ksi).
Which condition does FabDigit quote by default, Annealed or CW-TR?
Annealed is the default S32001 condition in the FabDigit quote flow. 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 is easier to machine, S32001 Annealed or S32001 CW-TR?
S32001 Annealed, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for S32001 CW-TR; for welding the order is S32001 Annealed first (very good, 70/100) then S32001 CW-TR (good, 60/100).
