Steel 60Si2Mn Hardened & Tempered vs 60Si2Mn Hot Rolled
Steel · 60Si2Mn temper comparison
60Si2Mn Hardened & Tempered and 60Si2Mn Hot Rolled are two conditions of the same steel grade, 60Si2Mn: Hardened & Tempered (quenched and tempered) versus Hot Rolled. The chemistry is identical, so every difference below comes from the condition. 60Si2Mn Hardened & Tempered is the stronger of the two: yield strength 1,600 MPa (232 ksi) against 600 MPa (87 ksi) for 60Si2Mn Hot Rolled, about 167% more; tensile strength follows at 1,750 MPa (254 ksi) vs 1,000 MPa (145 ksi). In exchange, 60Si2Mn Hot Rolled is the more ductile: elongation 10% versus 6% for 60Si2Mn Hardened & Tempered, and 60Si2Mn Hot Rolled is harder (290 HB vs 255 HB). 60Si2Mn Hardened & Tempered runs hotter in service (250°C vs 200°C continuous). On the shop floor, 60Si2Mn Hot Rolled machines more easily (fair vs not recommended).
60Si2Mn Hardened & TemperedChoose it when strength drives the design, or when the part sees heat.
60Si2Mn Hot RolledChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
60Si2Mn Hardened & Tempered vs 60Si2Mn Hot Rolled: 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.

60Si2Mn Hardened & Tempered vs 60Si2Mn Hot Rolled — frequently asked
Is 60Si2Mn Hardened & Tempered stronger than 60Si2Mn Hot Rolled?
Yes. 60Si2Mn Hardened & Tempered has a typical yield strength of 1,600 MPa (232 ksi) against 600 MPa (87 ksi) for 60Si2Mn Hot Rolled — about 167% more. Tensile strength is 1,750 MPa (254 ksi) vs 1,000 MPa (145 ksi).
Which condition does FabDigit quote by default, Hardened & Tempered or Hot Rolled?
Annealed is the default 60Si2Mn condition in the FabDigit quote flow (neither Hardened & Tempered nor Hot Rolled). 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, 60Si2Mn Hardened & Tempered or 60Si2Mn Hot Rolled?
60Si2Mn Hot Rolled. Its machinability rates fair (38/100) against not recommended (12/100) for 60Si2Mn Hardened & Tempered; for welding the order is 60Si2Mn Hot Rolled first (poor, 18/100) then 60Si2Mn Hardened & Tempered (not recommended, 10/100).
