Stainless Steel 430FSe-A vs 430FSe-CD
Stainless Steel · 430FSe temper comparison
430FSe-A and 430FSe-CD are two conditions of the same stainless steel grade, 430FSe: A (solution annealed) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. 430FSe-CD is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 310 MPa (45 ksi) for 430FSe-A, about 77% more; tensile strength follows at 655 MPa (95 ksi) vs 520 MPa (75.4 ksi). In exchange, 430FSe-A is the more ductile: elongation 25% versus 15% for 430FSe-CD, and 430FSe-CD is harder (215 HB vs 175 HB).
430FSe-AChoose it when the part is bent, formed or impact-loaded.
430FSe-CDChoose it when strength drives the design.
430FSe-A vs 430FSe-CD: 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.

430FSe-A vs 430FSe-CD — frequently asked
Is 430FSe-CD stronger than 430FSe-A?
Yes. 430FSe-CD has a typical yield strength of 550 MPa (79.8 ksi) against 310 MPa (45 ksi) for 430FSe-A — about 77% more. Tensile strength is 655 MPa (95 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, A or CD?
A is the default 430FSe 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 430FSe-A over 430FSe-CD?
Pick 430FSe-A when the part is bent, formed or impact-loaded. Pick 430FSe-CD when strength drives the design.
