What is 2083 Annealed?

2083 Annealed is 2083 in the Annealed temper — standard mill-supplied condition for blocks and plate that will be rough-machined and then hardened by the toolmaker. 2083 Annealed has a yield strength of 480 MPa (69.6 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 60% of steel grades. Elongation at break is 16% and the elastic modulus is 215 GPa (31.2 Msi). 2083 Annealed has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 95% of steel grades. It melts at 1,450°C (2,642 °F).

Chemical & Environmental3

Corrosion resistance is fair (42/100), better than 98% of steel grades.

Chemical Resistance SummaryResists humid air, water, steam and off-gassing from PVC/POM if the surface is hardened and polished; attacked by chlorides, seawater, mineral acids and prolonged condensate — passivity is much poorer in the annealed or ground-rough state.

Working with 2083 Annealed

Is 2083 easy to machine?

Machine in the annealed state with sharp, positive-rake carbide and generous coolant — 13Cr steel work-hardens and smears; above ~48 HRC switch to grinding, EDM or ceramic/CBN hard-milling.

Can 2083 be welded?

Poor weldability: preheat 250–350 °C, use matching 13Cr or 410NiMo filler, weld hot and immediately re-temper; laser/TIG mould repair with post-weld temper below the tempering temperature.

Can 2083 be formed, bent or molded?

Supplied as blocks/plate for hot work only; forge 1050–850 °C with slow cooling, then soft anneal 750–800 °C, and expect ~0.1 % dimensional change plus distortion on hardening from 1020–1050 °C (vacuum quench preferred).

What surface finishes work on 2083?

Excellent for mirror polishing and photo-etch texturing when hardened; can be nitrided or hard-chrome/PVD coated, but avoid electroless processes that trap hydrogen and always temper after grinding.

2083 Annealed — frequently asked

What is 2083 Annealed used for?

2083 Annealed is typically used for plastic mould cavity plates, optical and lens moulds, medical plastic moulds, mould cores and slides, tooling for PVC and other corrosive polymers and textured cosmetic-part moulds. In short: workhorse mold-cavity plate.

What is the yield strength of 2083 Annealed?

2083 Annealed has a typical yield strength of 480 MPa (69.6 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 60% of steel grades. Strength varies by condition: see the 5 listed tempers.

Is 2083 Annealed easy to machine?

Not especially — machinability is rated fair (40/100, worse than 76% of steel grades). Machine in the annealed state with sharp, positive-rake carbide and generous coolant — 13Cr steel work-hardens and smears; above ~48 HRC switch to grinding, EDM or ceramic/CBN hard-milling.

Can 2083 Annealed be welded?

Not readily — weldability is rated poor (25/100). Poor weldability: preheat 250–350 °C, use matching 13Cr or 410NiMo filler, weld hot and immediately re-temper; laser/TIG mould repair with post-weld temper below the tempering temperature.

What surface finishes work on 2083 Annealed?

Excellent for mirror polishing and photo-etch texturing when hardened; can be nitrided or hard-chrome/PVD coated, but avoid electroless processes that trap hydrogen and always temper after grinding.

Can 2083 Annealed be formed, bent or molded?

Supplied as blocks/plate for hot work only; forge 1050–850 °C with slow cooling, then soft anneal 750–800 °C, and expect ~0.1 % dimensional change plus distortion on hardening from 1020–1050 °C (vacuum quench preferred).

What is the maximum service temperature of 2083 Annealed?

2083 Annealed is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

What is the difference between 2083 Annealed and 2083 Prehard?

Annealed is the default condition — standard mill-supplied condition for blocks and plate that will be rough-machined and then hardened by the toolmaker. Prehard: pick when the cavity is machined to final size and no in-house heat treatment (and no distortion) is acceptable; corrosion resistance without hardening cost. Yield strength is 480 MPa in Annealed versus 850 MPa in Prehard.
