Steel 2316 Annealed vs 2316 Q&T
Steel · 2316 temper comparison
2316 Annealed and 2316 Q&T are two conditions of the same steel grade, 2316: Annealed versus Q&T (quenched and tempered). The chemistry is identical, so every difference below comes from the condition. 2316 Q&T is the stronger of the two: yield strength 1,350 MPa (196 ksi) against 520 MPa (75.4 ksi) for 2316 Annealed, about 160% more; tensile strength follows at 1,600 MPa (232 ksi) vs 780 MPa (113 ksi). In exchange, 2316 Annealed is the more ductile: elongation 18% versus 5% for 2316 Q&T, and 2316 Q&T is harder (460 HB vs 235 HB). 2316 Annealed runs hotter in service (400°C vs 200°C continuous). On the shop floor, 2316 Annealed machines more easily (fair vs poor).

2316 Annealed vs 2316 Q&T: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all 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.
