Steel 1.2080 Annealed vs 1.2080 Hot Rolled

Steel · 1.2080 temper comparison

1.2080 Annealed and 1.2080 Hot Rolled are two conditions of the same steel grade, 1.2080: Annealed versus Hot Rolled. 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 Annealed, about 25% more; tensile strength follows at 1,000 MPa (145 ksi) vs 850 MPa (123 ksi). In exchange, 1.2080 Annealed is the more ductile: elongation 12% versus 6% for 1.2080 Hot Rolled, and 1.2080 Hot Rolled is harder (300 HB vs 230 HB). On the shop floor, 1.2080 Annealed machines more easily (30 vs 18 out of 100).

1.2080 Annealed vs 1.2080 Hot Rolled — frequently asked

Is 1.2080 Hot Rolled stronger than 1.2080 Annealed?

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 Annealed — about 25% more. Tensile strength is 1,000 MPa (145 ksi) vs 850 MPa (123 ksi).

Which condition does FabDigit quote by default, Annealed or Hot Rolled?

Annealed is the default 1.2080 condition in the FabDigit quote flow. 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 Annealed or 1.2080 Hot Rolled?

1.2080 Annealed, by a small margin. Both rate poor for machinability — 30/100 against 18/100 for 1.2080 Hot Rolled; for welding the order is 1.2080 Annealed first (poor, 15/100) then 1.2080 Hot Rolled (not recommended, 8/100).
