Stainless Steel 303Se Annealed vs 303Se Cold Drawn High Tensile
Stainless Steel · 303Se temper comparison
303Se Annealed and 303Se Cold Drawn High Tensile are two conditions of the same stainless steel grade, 303Se: Annealed versus Cold Drawn High Tensile (heavily cold-drawn bar). The chemistry is identical, so every difference below comes from the condition. 303Se Cold Drawn High Tensile is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 240 MPa (34.8 ksi) for 303Se Annealed, about 158% more; tensile strength follows at 860 MPa (125 ksi) vs 620 MPa (89.9 ksi). In exchange, 303Se Annealed is the more ductile: elongation 50% versus 16% for 303Se Cold Drawn High Tensile, and 303Se Cold Drawn High Tensile is harder (270 HB vs 160 HB).
303Se AnnealedChoose it when the part is bent, formed or impact-loaded.
303Se Cold Drawn High TensileChoose it when strength drives the design.
303Se Annealed vs 303Se Cold Drawn High Tensile: 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.

303Se Annealed vs 303Se Cold Drawn High Tensile — frequently asked
Is 303Se Cold Drawn High Tensile stronger than 303Se Annealed?
Yes. 303Se Cold Drawn High Tensile has a typical yield strength of 620 MPa (89.9 ksi) against 240 MPa (34.8 ksi) for 303Se Annealed — about 158% more. Tensile strength is 860 MPa (125 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn High Tensile?
Cold Drawn is the default 303Se condition in the FabDigit quote flow (neither Annealed nor Cold Drawn High Tensile). 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.
When should I choose 303Se Annealed over 303Se Cold Drawn High Tensile?
Pick 303Se Annealed when the part is bent, formed or impact-loaded. Pick 303Se Cold Drawn High Tensile when strength drives the design.
