Black surface or Machined surface, UT 100% Passed
◆ Characteristics
1. With good hardenability and wear resistance.
2. With high oxidation resistance, good corrosion resistance after quenching and
polishing, small deformation after heat treatment.
◆ Applications
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
tools etc.

Thermal Annealing |
◆ Heat Treatment
Annealing |
800 to 850°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. 255 HB.
Stress relieving |
650 to 700°C
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.
Hardening |
1020 to 1040°C
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.
Tempering |
Slow heating to tempering temperature immediately after hardening/time in furnace
