Stainless Steel 410HT Annealed vs 410HT Q&T 36-42 HRC
Stainless Steel · 410HT temper comparison
410HT Annealed and 410HT Q&T 36-42 HRC are two conditions of the same stainless steel grade, 410HT: Annealed versus Q&T 36-42 HRC (hardened and low-temperature tempered). The chemistry is identical, so every difference below comes from the condition. 410HT Q&T 36-42 HRC is the stronger of the two: yield strength 1,035 MPa (150 ksi) against 300 MPa (43.5 ksi) for 410HT Annealed, about 3.5 times as much; tensile strength follows at 1,310 MPa (190 ksi) vs 490 MPa (71.1 ksi). In exchange, 410HT Annealed is the more ductile: elongation 25% versus 12% for 410HT Q&T 36-42 HRC, and 410HT Q&T 36-42 HRC is harder (375 HB vs 155 HB). 410HT Annealed runs hotter in service (650°C vs 400°C continuous). On the shop floor, 410HT Annealed machines more easily (fair vs poor).

410HT Annealed vs 410HT Q&T 36-42 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.
