Speciality

Low-sodium hydrogen drug coating Cr-Ni-Si-Mo valve surfacing electrode;

Surfacing metal is a small amount of ferrite austenite structure, has good high temperature resistance, erosion resistance and other properties, high temperature hardness, good thermal stability and thermal fatigue resistance.

With the increase of aging time, the hardness and abrasion resistance of surfacing metal are further improved.
