Stainless Steel 430FSe-A vs 430FSe-HR

Stainless Steel · 430FSe temper comparison

430FSe-A and 430FSe-HR are two conditions of the same stainless steel grade, 430FSe: A (solution annealed) versus HR (hot rolled). The chemistry is identical, so every difference below comes from the condition. 430FSe-HR is the stronger of the two: yield strength 345 MPa (50 ksi) against 310 MPa (45 ksi) for 430FSe-A, about 11% more; tensile strength follows at 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi). In exchange, 430FSe-A is the more ductile: elongation 25% versus 22% for 430FSe-HR, and 430FSe-HR is harder (185 HB vs 175 HB).

430FSe-AChoose it when the part is bent, formed or impact-loaded.

430FSe-HRChoose it when strength drives the design.

430FSe-A vs 430FSe-HR — frequently asked

Is 430FSe-HR stronger than 430FSe-A?

Yes. 430FSe-HR has a typical yield strength of 345 MPa (50 ksi) against 310 MPa (45 ksi) for 430FSe-A — about 11% more. Tensile strength is 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi).

Which condition does FabDigit quote by default, A or HR?

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-HR?

Pick 430FSe-A when the part is bent, formed or impact-loaded. Pick 430FSe-HR when strength drives the design.
