With good hardenability and wear resistance.2. With high oxidation resistance, good corrosion resistance after quenching and polishing, small deformation after heat treatment. ApplicationsFor making different kinds of cold work molds with high accuracy and long service life, cutting tools and measuring instruments, such as complex-shaped piercing dies, threading screw plates, cold extrusion dies, cold cutting scissors, precision measuring tools etc. Forging TechniqueHeatTemperatureStart ForgingTemperatureFinish ForgingTemperatureCooling Method1120-1160 °C1050-1090 °C≥850 °CThermal Annealing Heat TreatmentAnnealing800 to 850°CSlow 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. 255 HB. Stress relieving650 to 700°CSlow cooling in furnace; intended to relieve stresses set up by extensive machining, or incomplex shapes. After through heating, hold in neutral atmosphere for 1 to 2 hours. Hardening1020 to 1040°CComplex shapes/air, simple shapes/air blast, oil, salt bath from (220 to 250°C or 500 to 550°C).Holding time after temperature equalization: 15 to 30 minutes.Obtainable hardness: 63 - 65 HRC. TemperingSlow heating to tempering temperature immediately after hardening/time in furnace 1hour for each 20 mm of work piece thickness, but at least 2 hours/cooling in air. For average hardness figures to be obtained, please refer to the tempering chart. For certain cases we recommend to reduce tempering temperature and increase holding time. For certain applications requiring improved retention of hardness, a nitriding treatmentis recommended. What we can offerWhat we can offer?
