Stainless Steel 416 Annealed vs 416 Hardened & Tempered
Stainless Steel · 416 temper comparison
416 Annealed and 416 Hardened & Tempered are two conditions of the same stainless steel grade, 416: Annealed versus Hardened & Tempered (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 416 Hardened & Tempered is the stronger of the two: yield strength 700 MPa (102 ksi) against 275 MPa (39.9 ksi) for 416 Annealed, about 155% more; tensile strength follows at 900 MPa (131 ksi) vs 515 MPa (74.7 ksi). In exchange, 416 Annealed is the more ductile: elongation 30% versus 18% for 416 Hardened & Tempered, and 416 Hardened & Tempered is harder (285 HB vs 155 HB). 416 Annealed runs hotter in service (650°C vs 500°C continuous). On the shop floor, 416 Annealed machines more easily (very good vs good).
416 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
416 Hardened & TemperedChoose it when strength drives the design.
416 Annealed vs 416 Hardened & Tempered: 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.
