Stainless Steel 430F Cold Drawn vs 430F Hot Rolled
Stainless Steel · 430F temper comparison
430F Cold Drawn and 430F Hot Rolled are two conditions of the same stainless steel grade, 430F: Cold Drawn versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 430F Cold Drawn is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 400 MPa (58 ksi) for 430F Hot Rolled, about 38% more; tensile strength follows at 660 MPa (95.7 ksi) vs 580 MPa (84.1 ksi). In exchange, 430F Hot Rolled is the more ductile: elongation 22% versus 15% for 430F Cold Drawn, and 430F Cold Drawn is harder (235 HB vs 190 HB).
430F Cold DrawnChoose it when strength drives the design.
430F Hot RolledChoose it when the part is bent, formed or impact-loaded.
430F Cold Drawn vs 430F Hot Rolled: 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.

430F Cold Drawn vs 430F Hot Rolled — frequently asked
Is 430F Cold Drawn stronger than 430F Hot Rolled?
Yes. 430F Cold Drawn has a typical yield strength of 550 MPa (79.8 ksi) against 400 MPa (58 ksi) for 430F Hot Rolled — about 38% more. Tensile strength is 660 MPa (95.7 ksi) vs 580 MPa (84.1 ksi).
Which condition does FabDigit quote by default, Cold Drawn or Hot Rolled?
Annealed is the default 430F condition in the FabDigit quote flow (neither Cold Drawn nor Hot Rolled). 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, 430F Cold Drawn or 430F Hot Rolled?
430F Cold Drawn, by a small margin. Both rate very good for machinability — 76/100 against 70/100 for 430F Hot Rolled.
