Steel AF1410 Annealed vs AF1410 SHT-Q
Steel · AF1410 temper comparison
AF1410 Annealed and AF1410 SHT-Q are two conditions of the same steel grade, AF1410: Annealed versus SHT-Q (austenitized 830 °C, quenched + refrigerated). The chemistry is identical, so every difference below comes from the condition. AF1410 SHT-Q is the stronger of the two: yield strength 970 MPa (141 ksi) against 830 MPa (120 ksi) for AF1410 Annealed, about 17% more; tensile strength follows at 1,310 MPa (190 ksi) vs 1,030 MPa (149 ksi). In exchange, AF1410 Annealed is the more ductile: elongation 20% versus 18% for AF1410 SHT-Q, and AF1410 SHT-Q is harder (41 HRC vs 31 HRC). AF1410 Annealed runs hotter in service (400°C vs 200°C continuous). On the shop floor, AF1410 Annealed machines more easily (fair vs poor).
AF1410 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
AF1410 SHT-QChoose it when strength drives the design.
AF1410 Annealed vs AF1410 SHT-Q: 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.
