Stainless Steel 430F Annealed vs 430F Cold Drawn
Stainless Steel · 430F temper comparison
430F Annealed and 430F Cold Drawn are two conditions of the same stainless steel grade, 430F: Annealed versus Cold Drawn. 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 380 MPa (55.1 ksi) for 430F Annealed, about 45% more; tensile strength follows at 660 MPa (95.7 ksi) vs 550 MPa (79.8 ksi). In exchange, 430F Annealed is the more ductile: elongation 25% versus 15% for 430F Cold Drawn, and 430F Cold Drawn is harder (235 HB vs 175 HB).
430F AnnealedChoose it when the part is bent, formed or impact-loaded.
430F Cold DrawnChoose it when strength drives the design.
430F Annealed vs 430F Cold Drawn: 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 Annealed vs 430F Cold Drawn — frequently asked
Is 430F Cold Drawn stronger than 430F Annealed?
Yes. 430F Cold Drawn has a typical yield strength of 550 MPa (79.8 ksi) against 380 MPa (55.1 ksi) for 430F Annealed — about 45% more. Tensile strength is 660 MPa (95.7 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, Annealed or Cold Drawn?
Annealed is the default 430F 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 430F Annealed over 430F Cold Drawn?
Pick 430F Annealed when the part is bent, formed or impact-loaded. Pick 430F Cold Drawn when strength drives the design.
