Stainless Steel 410 Annealed vs 410 Hardened & Tempered

Stainless Steel · 410 temper comparison

410 Annealed and 410 Hardened & Tempered are two conditions of the same stainless steel grade, 410: Annealed versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 410 Hardened & Tempered is the stronger of the two: yield strength 700 MPa (102 ksi) against 310 MPa (45 ksi) for 410 Annealed, about 126% more; tensile strength follows at 900 MPa (131 ksi) vs 517 MPa (75 ksi). In exchange, 410 Annealed is the more ductile: elongation 25% versus 18% for 410 Hardened & Tempered, and 410 Hardened & Tempered is harder (285 HB vs 155 HB). 410 Annealed runs hotter in service (650°C vs 540°C continuous). On the shop floor, 410 Annealed machines more easily (good vs fair) and 410 Annealed welds better (45 vs 35 out of 100).

410 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

410 Hardened & TemperedChoose it when strength drives the design.
