Stainless Steel A286 Age Hardened vs A286 Solution Annealed

Stainless Steel · A286 temper comparison

A286 Age Hardened and A286 Solution Annealed are two conditions of the same stainless steel grade, A286: Age Hardened (solution treated + 720 °C / 16 h aged) versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. A286 Age Hardened is the stronger of the two: yield strength 725 MPa (105 ksi) against 310 MPa (45 ksi) for A286 Solution Annealed, about 134% more; tensile strength follows at 1,035 MPa (150 ksi) vs 690 MPa (100 ksi). In exchange, A286 Solution Annealed is the more ductile: elongation 40% versus 22% for A286 Age Hardened, and A286 Age Hardened is harder (300 HB vs 170 HB).

A286 Age HardenedChoose it when strength drives the design.

A286 Solution AnnealedChoose it when the part is bent, formed or impact-loaded.
