Stellite
Cobalt base Alloy can resist against various kinds of abrasion,corrosion,high-temperature oxidation with offering high hardness and hot hardness, excellent high-temperature strength and thermal fatigue resistance and high shock resistance.
Most used to making as the sparts which need working under anti-abrasion, anti-corrosion,anti-grain, metal abrasion, anti- high temperature,anti-high impaction working environment.
Main products: Cobalt Bare welding sticks, Cobalt-base alloy Welding Powder , Cobalt-base Electrode welding rods, Cobalt-base Precision Casting and wrought alloys. Application :stellite alloy valve inserts, pressure cap and oil equipment parts etc.
