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.
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.
Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 212
Density [g/cm3]: 7.65
Thermal conductivity [W/m.K]: 18
Electric resistivity [Ohm mm2/m]: 0.65
Specific heat capacity[J/g.K]: 460
Coefficient of Linear Thermal Expansion 10-6 oC-1
Heat to 760-780oC, cool slowly. This will produce a maximum Brinell hardness of 230.
Preheating: 800oC. Harden from a temperature of 1000-1050oC followed by oil, or polymer cooling bath. Hardness after quenching is 51-55 HRC.
Tempering temperature: 150-200oC.
Hot forming temperature: 1050-850oC, slow cooling.
Very good machinability.
