Heat treatment
Annealing Treatment
Uniform annealing and internal stress removal are available by continuous anneal furnace. Bright anneal is available in hydrogenous atmosphere.(hydrogen purity 99.999% Upper temperature limit 1100℃) Also with our batch furnace, heat treatment which needs the temperature to be kept the same for long hours is also available.
Vacuum treatment
With heat treatment under high vacuum, gasification and removal of impurities intervening in metallic crystal grain boundary can be done. (vacuum 1 x 10-6A Upper temperature limit 900℃)
Chemical polishing
