We offer two conditions of steel grade of 1.2085
Annealed: Hardness≤235HB
Q+T: Hardness 33-38HRC or as customized
DIN 1.2085 is a kind of Corrosion-resistant tool steel with sulphur for plastic molds as well as aggressive plastics
and for application fields, where a corrosion resistance, good machinability and good mechanical properties are important. The same properties like 1.2316 with the addition of sulphur.
DIN 1.2085 is mainly used in processes with chemically aggressive and acidic thermoplastics, PVC-aminoplastics, plastics for injection mold inserts or for special machine parts in the food industry. Used also in the application field
of the automobile industry and machine construction.

AnnealingHeat Treatment
840 to 870°C
Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air.
Hardness after annealing: max. 229 HB.
Stress relieving
Approx. 650°C
Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes.
After through heating, hold in neutral atmosphere for 1 - 2 hours.
Hardening
1000 to 1050°C / Oil, air
Holding time after temperature equalization: 15 to 30 minutes.
Obtainable hardness: 53-56 HRC
Tempering
100 to 200°C (212 to 392°F)
Slow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness but at least 2 hours / cooling in air.
