Working with 1.2080 Hot Rolled
Is 1.2080 easy to machine?
Machine only in the annealed state with rigid setups, coated carbide and low speeds; the 12-15 % carbide volume abrades tooling badly — hardened parts are finished by grinding, wire EDM or CBN.
Can 1.2080 be welded?
Essentially unweldable structurally; repair only with matching high-alloy electrode at 300-400 °C preheat, immediate temper, and expect hardness/crack sensitivity.
Can 1.2080 be formed, bent or molded?
Hot work between 1050 and 900 °C with slow furnace cooling; no meaningful cold forming — oil quench from 940-970 °C causes more distortion than air-hardening D2, so allow grinding stock.
What surface finishes work on 1.2080?
Takes a high polish when hardened; protect against rust with oiling, black oxide or phosphating, and extend die life with nitriding or TiN/TiCN/CrN PVD below the tempering temperature.

1.2080 Hot Rolled — frequently asked
What is 1.2080 Hot Rolled used for?
1.2080 Hot Rolled is typically used for cold blanking and cutting dies, shear blades, thread rolling dies, cold drawing and forming tools, forming rollers and punches and die inserts. In short: cold-work die tool.
What is the yield strength of 1.2080 Hot Rolled?
1.2080 Hot Rolled has a typical yield strength of 650 MPa (94.3 ksi) and a tensile strength of 1,000 MPa (145 ksi) — stronger than 79% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.2080 Hot Rolled easy to machine?
Not especially — machinability is rated poor (18/100, worse than 97% of steel grades). Machine only in the annealed state with rigid setups, coated carbide and low speeds; the 12-15 % carbide volume abrades tooling badly — hardened parts are finished by grinding, wire EDM or CBN.
Can 1.2080 Hot Rolled be welded?
Not readily — weldability is rated not recommended (8/100). Essentially unweldable structurally; repair only with matching high-alloy electrode at 300-400 °C preheat, immediate temper, and expect hardness/crack sensitivity.
What surface finishes work on 1.2080 Hot Rolled?
Takes a high polish when hardened; protect against rust with oiling, black oxide or phosphating, and extend die life with nitriding or TiN/TiCN/CrN PVD below the tempering temperature.
Can 1.2080 Hot Rolled be formed, bent or molded?
Hot work between 1050 and 900 °C with slow furnace cooling; no meaningful cold forming — oil quench from 940-970 °C causes more distortion than air-hardening D2, so allow grinding stock.
What is the maximum service temperature of 1.2080 Hot Rolled?
1.2080 Hot Rolled is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in 1.2080 Hot Rolled?
Yes — 1.2080 Hot Rolled is available for CNC machining; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
