Steel 60# Hardened vs 60# Induction Hardened
Steel · 60# temper comparison
60# Hardened and 60# Induction Hardened are two conditions of the same steel grade, 60#: Hardened versus Induction Hardened. The chemistry is identical, so every difference below comes from the condition. 60# Hardened is the stronger of the two: yield strength 1,700 MPa (247 ksi) against 700 MPa (102 ksi) for 60# Induction Hardened, about 143% more; tensile strength follows at 2,100 MPa (305 ksi) vs 950 MPa (138 ksi). In exchange, 60# Induction Hardened is the more ductile: elongation 12% versus 1% for 60# Hardened, and 60# Hardened is harder (650 HB vs 280 HB). 60# Induction Hardened runs hotter in service (200°C vs 180°C continuous) and 60# Induction Hardened conducts electricity better (9 % IACS vs 8 % IACS).
60# HardenedChoose it when strength drives the design.
60# Induction HardenedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
60# Hardened vs 60# 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.

60# Hardened vs 60# Induction Hardened — frequently asked
Is 60# Hardened stronger than 60# Induction Hardened?
Yes. 60# Hardened has a typical yield strength of 1,700 MPa (247 ksi) against 700 MPa (102 ksi) for 60# Induction Hardened — about 143% more. Tensile strength is 2,100 MPa (305 ksi) vs 950 MPa (138 ksi).
Which condition does FabDigit quote by default, Hardened or Induction Hardened?
Annealed is the default 60# condition in the FabDigit quote flow (neither Hardened nor Induction Hardened). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, 60# Hardened or 60# Induction Hardened?
60# Induction Hardened. Its machinability rates poor (15/100) against not recommended (10/100) for 60# Hardened.
