Steel 1.2080 Hot Rolled vs 1.2080 Q&T 60-62 HRC
Steel · 1.2080 temper comparison
1.2080 Hot Rolled and 1.2080 Q&T 60-62 HRC are two conditions of the same steel grade, 1.2080: Hot Rolled versus Q&T 60-62 HRC (oil quench + 200-230 °C temper). The chemistry is identical, so every difference below comes from the condition. 1.2080 Hot Rolled is the stronger of the two: yield strength 650 MPa (94.3 ksi) against 520 MPa (75.4 ksi) for 1.2080 Q&T 60-62 HRC, about 25% more. 1.2080 Hot Rolled is the more ductile: elongation 6% versus 1% for 1.2080 Q&T 60-62 HRC, and 1.2080 Hot Rolled is harder (300 HB vs 230 HB). 1.2080 Hot Rolled runs hotter in service (200°C vs 180°C continuous). On the shop floor, 1.2080 Hot Rolled machines more easily (poor vs not recommended).

1.2080 Hot Rolled vs 1.2080 Q&T 60-62 HRC: 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.

1.2080 Hot Rolled vs 1.2080 Q&T 60-62 HRC — frequently asked
Is 1.2080 Hot Rolled stronger than 1.2080 Q&T 60-62 HRC?
Yes. 1.2080 Hot Rolled has a typical yield strength of 650 MPa (94.3 ksi) against 520 MPa (75.4 ksi) for 1.2080 Q&T 60-62 HRC — about 25% more. Tensile strength is 1,000 MPa (145 ksi) vs 2,150 MPa (312 ksi).
Which condition does FabDigit quote by default, Hot Rolled or Q&T 60-62 HRC?
Annealed is the default 1.2080 condition in the FabDigit quote flow (neither Hot Rolled nor Q&T 60-62 HRC). 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, 1.2080 Hot Rolled or 1.2080 Q&T 60-62 HRC?
1.2080 Hot Rolled. Its machinability rates poor (18/100) against not recommended (6/100) for 1.2080 Q&T 60-62 HRC; for welding the order is 1.2080 Q&T 60-62 HRC first (poor, 15/100) then 1.2080 Hot Rolled (not recommended, 8/100).
