Stainless Steel 416 Hardened & Tempered vs 416 Q&T 38-44 HRC
Stainless Steel · 416 temper comparison
416 Hardened & Tempered and 416 Q&T 38-44 HRC are two conditions of the same stainless steel grade, 416: Hardened & Tempered (quenched and tempered) versus Q&T 38-44 HRC (hardened, tempered 200–300 °C). The chemistry is identical, so every difference below comes from the condition. 416 Q&T 38-44 HRC is the stronger of the two: yield strength 1,080 MPa (157 ksi) against 700 MPa (102 ksi) for 416 Hardened & Tempered, about 54% more; tensile strength follows at 1,310 MPa (190 ksi) vs 900 MPa (131 ksi). In exchange, 416 Hardened & Tempered is the more ductile: elongation 18% versus 10% for 416 Q&T 38-44 HRC, and 416 Hardened & Tempered is harder (285 HB vs 155 HB). 416 Hardened & Tempered runs hotter in service (500°C vs 300°C continuous). On the shop floor, 416 Hardened & Tempered machines more easily (good vs poor).

416 Hardened & Tempered vs 416 Q&T 38-44 HRC: 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.
