Introduction	Cold heading steel, with the characteristics of high strength and high hardness, is a special material used for the manufacture of cutting tools such as saw blade.

 

Heat Treatment
Normalizing For 15CrNi6
    Nominal normalizing temperature:850-880°C
    Hold the temperature for several hours
    Cooling in the air
Annealing  For 15CrNi6
    Nominal Annealing temperature:650-700°C
    Cool slowly in the furance
    Maximum Brinell hardness of 229
Hardening and Tempering(QT)  For 15CrNi6
    Nominal Hardening temperature:820-870°C
    Hold at this temperature then quench in oil or water
    Tempering  as soon as possible when the temperature low to ambient
    Heat uniformly to the suitable temperature.
    keep the material out of the furnace ,then cool in the air
Mechanical Property( for reference only)
    Tensile strength: 880-1100MPa
    Yield point: 635MPa
    Percentage reduction of area after fracture: 40%
    Elongation after fracture: 11%
    Impact test (+20°C):  Longitud - 40~60J
