Industry’s single source for heat treat and melting solutions
Industrial Tempering Furnace
Tempering Process
The tempering process is used to reduce the brittleness in hardened steel and to remove the internal strains caused by the sudden cooling in a quenching bath. During the tempering process the metal being treated is heated in a temper furnace to a specified temperature for a period of time based on the desired level of hardness, strength, and ductility. Higher tempering temperatures will result in high ductility, but low strength and hardness. Lower tempering temperatures will result in low ductility, but high strength and hardness.
