Steel group: Cold work tool steels
Properties: Cold work tool steel with high thoughness and full hardenability, for air hardening.
Applications: Highly stres sed coi ning tools, cut lery dies, hobbing tools, cold she ar bla des for heavy-gauge ma terial, plas tic moulds.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 840 to 870°C / Air, oil. Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 54 - 58 HRC in air, 55 - 59 HRC in oil.
Tempering: Slow heating to tempering temperature immediately after hardening/time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours/cool ing in air. For average hardness figures to beobtained please refer to the tempering chart. For certain cases we recommend to reduce tempering temperature and in crease holding time.
Diagram note: Tempering chart: Hardening tem perature: 850°C. Specimen size: square 20 mm.
