Stainless Steel 416Se Hardened & Tempered vs 416Se Stress Relieved
Stainless Steel · 416Se temper comparison
416Se Hardened & Tempered and 416Se Stress Relieved are two conditions of the same stainless steel grade, 416Se: Hardened & Tempered (quenched and tempered) versus Stress Relieved. The chemistry is identical, so every difference below comes from the condition. 416Se Hardened & Tempered is the stronger of the two: yield strength 760 MPa (110 ksi) against 380 MPa (55.1 ksi) for 416Se Stress Relieved, about 100% more; tensile strength follows at 965 MPa (140 ksi) vs 560 MPa (81.2 ksi). In exchange, 416Se Stress Relieved is the more ductile: elongation 22% versus 17% for 416Se Hardened & Tempered, and 416Se Hardened & Tempered is harder (300 HB vs 180 HB). 416Se Stress Relieved runs hotter in service (675°C vs 480°C continuous). On the shop floor, 416Se Stress Relieved machines more easily (very good vs good).
416Se Hardened & TemperedChoose it when strength drives the design.
416Se Stress RelievedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
416Se Hardened & Tempered vs 416Se Stress Relieved: 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.
