Working with 1.2080 Q&T + Cryo 63-65 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.

1.2080 Q&T + Cryo 63-65 HRC — frequently asked

What is 1.2080 Q&T + Cryo 63-65 HRC used for?

1.2080 Q&T + Cryo 63-65 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 + Cryo 63-65 HRC?

1.2080 Q&T + Cryo 63-65 HRC has a typical yield strength of 1,800 MPa (261 ksi) and a tensile strength of 2,000 MPa (290 ksi) — stronger than 99% of steel grades. Strength varies by condition: see the 7 listed tempers.

Is 1.2080 Q&T + Cryo 63-65 HRC easy to machine?

Not especially — machinability is rated not recommended (5/100, 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 + Cryo 63-65 HRC be welded?

Not readily — weldability is rated not recommended (5/100). 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 + Cryo 63-65 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 + Cryo 63-65 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 + Cryo 63-65 HRC?

1.2080 Q&T + Cryo 63-65 HRC is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

Can FabDigit make parts in 1.2080 Q&T + Cryo 63-65 HRC?

Yes — 1.2080 Q&T + Cryo 63-65 HRC 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.
