VACUUM HEAT TREATING

Heating in a vacuum is carried out in steps up to the austenitization temperature, subsequently quenching by means of the insufflation of pure gaseous nitrogen at pressures ranging from 2 to 15 bar, according to the material and specifications to be obtained. Several temperings follow, which ensure the correct metallurgical structure.
Tempra in Vuoto

THIS IS APPLIED IN:

  • special steels for cold working
  • special steels for hot working
  • high speed steels
  • martensitic stainless steels
  • steels obtained from powder metallurgy
  • construction steels
  • bright annealing

WITH THE ADVANTAGE OF:

  • absence of decarburization during the process
  • lack of oxidation
  • containment of deformations
  • elimination of abrasive blasting downstream of the treatment
