Description
Martensitic stainless steel resistant to corrosion. 1.2085 steel displays the best corrosion resistance in hardened condition with a surface polished to give a mirror finisih. Properties: Magnetizable steelm good mechanical resistance and toughness, excellent for manufacturing of components that have to resist to aggressive plastics, good tool machinability thanks to its sulphur content, suitable for working in wet atmosphere and moisture, suitable for polishing, wear and corrosion proof, and very stable dimensionally during heat treatment.
Applications
All kinds of cutting tools - dies and die-blocks in the plastics industry such as PVC, knives, shears, surgical instruments, moulds for plastics production, as well as for surgical instruments and measuring gauges.

Soft Annealing
Heat to 760-780oC, cool slowly. This will produce a maximum Brinell hardness of 230.
Hardening
Preheating: 800oC. Harden from a temperature of 1000-1050oC followed by oil, or polymer cooling bath. Hardness after quenching is 51-55 HRC.
Tempering
Tempering temperature: 150-200oC.
Forging
Hot forming temperature: 1050-850oC, slow cooling.
Machinability
Very good machinability.
