Bright Annealing Oven 2

Bright annealing oven and furnace TH03

Introduction of annealing furnace

The Mesh belt bright annealing Furnace with protective atmosphere is mainly used for nickel-based alloy and austenitic stainless steel tubes, after annealing, the surface is uniformly bright without oxidation and oxidative stain.

Note: Before annealing, the inner and outer surfaces of the tubes of following materials must be cleaned by degreasing, and dried without any oxide. Then you can put the tubes into the annealing furnace.

Heat treatment steel grades: Ni-based alloys tube, 301 304 304L 316 316L 321
Heating element length: 0.6m - 8m
