1. With good hardenability and wear resistance.
2. With high oxidation resistance, good corrosion resistance after quenching and
polishing, small deformation after heat treatment.
For 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
|1120-1160 °C||1050-1090 °C||≥850 °C||Thermal Annealing|
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. 255 HB.
Slow 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.
Complex 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.
Slow 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
For certain applications requiring improved retention of hardness, a nitriding treatment
