What is 1.2080 Annealed?
1.2080 Annealed is 1.2080 in the Annealed temper — standard delivery condition of bar, flat and plate; machine and wire-EDM in this state, then harden. 1.2080 Annealed has a yield strength of 520 MPa (75.4 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 67% of steel grades. Elongation at break is 12% and the elastic modulus is 210 GPa (30.5 Msi). 1.2080 Annealed has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 95% of steel grades. It melts at 1,230°C (2,246 °F).

Working with 1.2080 Annealed
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 Annealed — frequently asked
What is 1.2080 Annealed used for?
1.2080 Annealed 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 Annealed?
1.2080 Annealed has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 67% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.2080 Annealed easy to machine?
Not especially — machinability is rated poor (30/100, worse than 89% 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 Annealed be welded?
Not readily — weldability is rated not recommended (10/100). 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 Annealed?
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 Annealed 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 Annealed?
1.2080 Annealed 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.
