Stainless Steel 416 Q&T 32-38 HRC vs 416 Q&T 38-44 HRC
Stainless Steel · 416 temper comparison
416 Q&T 32-38 HRC and 416 Q&T 38-44 HRC are two conditions of the same stainless steel grade, 416: Q&T 32-38 HRC (quenched and tempered ~500–550 °C) 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 930 MPa (135 ksi) for 416 Q&T 32-38 HRC, about 16% more; tensile strength follows at 1,310 MPa (190 ksi) vs 1,100 MPa (160 ksi). In exchange, 416 Q&T 32-38 HRC is the more ductile: elongation 14% versus 10% for 416 Q&T 38-44 HRC. 416 Q&T 32-38 HRC runs hotter in service (425°C vs 300°C continuous). On the shop floor, 416 Q&T 32-38 HRC machines more easily (fair vs poor).
416 Q&T 32-38 HRCChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
416 Q&T 38-44 HRCChoose it when strength drives the design.
416 Q&T 32-38 HRC 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.
