Product Description
DIN 1.2085 SUS420F 3Cr17+S Plastic Mould Steel Plate
1: DIN 1.2085 Steel Introduction
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.

7: DIN 1.2085 Steel Application
DIN 1.2085 is applicable for 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.plates for corrosion resistant mould bases and die sets; moulds for corrosive plastics; the expense for protection and care of mould tools is reduced thanks to increased corrosion resistance; not suitable for mould inserts.
8: DIN 1.2085 Steel Heat Treatment
Usually no heat treatment is required
Soft annealing:
850 to 880 °C for about 2 to 5 hours
slow controlled cooling, further cooling in air, annealing hardness max. 240 HB
Hardening:
1000 to 1030 °C
keeping curing temperature for 30 minutes
quenching in oil is preferable
obtainable hardness: 48 HRC
Tempering:
slow heating to tempering temperature immediately after hardening;
minimum time in furnace: 2 hour per 20 mm part thickness;
tempering twice is recommended
