Heat Treatment Processes
Normalizing
  • Nominal normalizing temperature: 840-890°C
  • Hold the temperature for several hours
  • Cooling in the air
Annealing
  • Nominal annealing temperature: 630-650°C
  • Cool slowly in the furnace
  • Maximum Brinell hardness of 229
Hardening and Tempering (QT)
  • Nominal hardening temperature: 830-865°C
  • Hold at this temperature then quench in oil
  • Temper as soon as possible when temperature lowers to ambient temperature
  • Heat the steel carefully to a suitable temperature selected by reference to a tempering chart or table
  • The usual tempering temperature is 600°C depending on actual requirements
  • Keep the material out of the furnace, then cool in the air
Mechanical Properties (Reference Only)
  • Tensile strength: 980-1270MPa
  • Yield point: 780MPa
  • Percentage reduction of area after fracture: 40%
