Stainless Steel 904L Cold Drawn vs 904L Cold Rolled Hard
Stainless Steel · 904L temper comparison
904L Cold Drawn and 904L Cold Rolled Hard are two conditions of the same stainless steel grade, 904L: Cold Drawn versus Cold Rolled Hard (cold rolled strip/sheet, temper rolled). The chemistry is identical, so every difference below comes from the condition. 904L Cold Rolled Hard is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 550 MPa (79.8 ksi) for 904L Cold Drawn, about 13% more; tensile strength follows at 820 MPa (119 ksi) vs 750 MPa (109 ksi). In exchange, 904L Cold Drawn is the more ductile: elongation 25% versus 15% for 904L Cold Rolled Hard, and 904L Cold Rolled Hard is harder (260 HB vs 230 HB). 904L Cold Drawn runs hotter in service (400°C vs 300°C continuous).
904L Cold DrawnChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
904L Cold Rolled HardChoose it when strength drives the design.
904L Cold Drawn vs 904L Cold Rolled Hard: 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.

904L Cold Drawn vs 904L Cold Rolled Hard — frequently asked
Is 904L Cold Rolled Hard stronger than 904L Cold Drawn?
Yes. 904L Cold Rolled Hard has a typical yield strength of 620 MPa (89.9 ksi) against 550 MPa (79.8 ksi) for 904L Cold Drawn — about 13% more. Tensile strength is 820 MPa (119 ksi) vs 750 MPa (109 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Cold Rolled Hard?
Solution Annealed is the default 904L condition in the FabDigit quote flow (neither Cold Drawn nor Cold Rolled Hard). 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, 904L Cold Drawn or 904L Cold Rolled Hard?
904L Cold Drawn. Its weldability rates very good (78/100) against very good (70/100) for 904L Cold Rolled Hard.
