Steel 49MnVS3 Annealed vs 49MnVS3 Induction Hardened
Steel · 49MnVS3 temper comparison
49MnVS3 Annealed and 49MnVS3 Induction Hardened are two conditions of the same steel grade, 49MnVS3: Annealed versus Induction Hardened. The chemistry is identical, so every difference below comes from the condition. 49MnVS3 Induction Hardened is the stronger of the two: yield strength 580 MPa (84.1 ksi) against 400 MPa (58 ksi) for 49MnVS3 Annealed, about 45% more; tensile strength follows at 900 MPa (131 ksi) vs 700 MPa (102 ksi). In exchange, 49MnVS3 Annealed is the more ductile: elongation 20% versus 10% for 49MnVS3 Induction Hardened, and 49MnVS3 Induction Hardened is harder (265 HB vs 200 HB). 49MnVS3 Annealed runs hotter in service (350°C vs 180°C continuous). On the shop floor, 49MnVS3 Annealed machines more easily (good vs poor) and 49MnVS3 Annealed welds better (poor vs not recommended).
49MnVS3 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
49MnVS3 Induction HardenedChoose it when strength drives the design.
49MnVS3 Annealed vs 49MnVS3 Induction Hardened: 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.
