Stainless Steel 430F Annealed vs 430F Hot Rolled

Stainless Steel · 430F temper comparison

430F Annealed and 430F Hot Rolled are two conditions of the same stainless steel grade, 430F: Annealed versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 430F Hot Rolled is the stronger of the two: yield strength 400 MPa (58 ksi) against 380 MPa (55.1 ksi) for 430F Annealed, about 5% more; tensile strength follows at 580 MPa (84.1 ksi) vs 550 MPa (79.8 ksi). In exchange, 430F Annealed is the more ductile: elongation 25% versus 22% for 430F Hot Rolled, and 430F Hot Rolled is harder (190 HB vs 175 HB).

430F AnnealedChoose it when the part is bent, formed or impact-loaded.

430F Hot RolledChoose it when strength drives the design.
