Stainless Steel 303Se Cold Drawn vs 303Se Cold Drawn High Tensile
Stainless Steel · 303Se temper comparison
303Se Cold Drawn and 303Se Cold Drawn High Tensile are two conditions of the same stainless steel grade, 303Se: Cold Drawn 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 415 MPa (60.2 ksi) for 303Se Cold Drawn, about 49% more; tensile strength follows at 860 MPa (125 ksi) vs 690 MPa (100 ksi). In exchange, 303Se Cold Drawn is the more ductile: elongation 35% versus 16% for 303Se Cold Drawn High Tensile, and 303Se Cold Drawn High Tensile is harder (270 HB vs 228 HB).
303Se Cold DrawnChoose it when the part is bent, formed or impact-loaded.
303Se Cold Drawn High TensileChoose it when strength drives the design.
303Se Cold Drawn 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 Cold Drawn vs 303Se Cold Drawn High Tensile — frequently asked
Is 303Se Cold Drawn High Tensile stronger than 303Se Cold Drawn?
Yes. 303Se Cold Drawn High Tensile has a typical yield strength of 620 MPa (89.9 ksi) against 415 MPa (60.2 ksi) for 303Se Cold Drawn — about 49% more. Tensile strength is 860 MPa (125 ksi) vs 690 MPa (100 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Cold Drawn High Tensile?
Cold Drawn is the default 303Se 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.
When should I choose 303Se Cold Drawn over 303Se Cold Drawn High Tensile?
Pick 303Se Cold Drawn when the part is bent, formed or impact-loaded. Pick 303Se Cold Drawn High Tensile when strength drives the design.
