Working with 1.2080 Q&T 60-62 HRC
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.

Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

1.2080 Q&T 60-62 HRC — frequently asked
What is 1.2080 Q&T 60-62 HRC used for?
1.2080 Q&T 60-62 HRC 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 Q&T 60-62 HRC?
1.2080 Q&T 60-62 HRC has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 2,150 MPa (312 ksi) — stronger than 67% of steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.2080 Q&T 60-62 HRC easy to machine?
Not especially — machinability is rated not recommended (6/100, worse than 100% 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 Q&T 60-62 HRC 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 Q&T 60-62 HRC?
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 Q&T 60-62 HRC 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 Q&T 60-62 HRC?
1.2080 Q&T 60-62 HRC is rated for continuous use to about 180°C (356 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
