wr6b,stellite6b
WR6B, Stellite6B alloy is one of the well-known cobalt-based wear-resistant alloys, you show wear resistance and strong resistance, can Xi most of the working conditions, widely used, hardness in 37-45HRC;It is mainly used for chemical wear-resistant plates, wear-resistant rods, steam chemical valve seats, steam turbine blade protection, wash-resistant bushings, hot-dip galvanized engulfing rollers and other partsCompared with WR6 (Stellite6), WR6B has better high-temperature wear resistance.
Superalloys are widely used in the manufacture of high-temperature components for gas turbines in the aeronautical, marine and industrial sectors, such as turbine blades, guide vanes, turbine discs, high-pressure compressor discs, combustion chambers, and the production of energy conversion. Spacecraft, rocket engines, nuclear reactors, petrochemical equipment, coal conversion and other equipment.

Stellite6b has the following features:
1.Abrasion resistance: Stellite6B has excellent abrasion resistance, especially suitable for high-temperature and high-speed friction and wear environments. It is resistant to wear, corrosion, oxidation and thermal fatigue.
2.High-temperature strength: Stellite 6B alloy retains high strength and hardness at high temperatures, making it ideal for high-temperature environments.
3.Corrosion resistance: Stellite 6B has good corrosion resistance and high stability against corrosive media such as acids, alkalis, salts, etc.
4.Thermal stability: The thermal stability of Stellite6B alloy is also one of its important properties. At high temperatures, the hardness and strength of the alloy will not be greatly affected, and good mechanical properties can be maintained. This thermal stability has led to the wide application of the alloy in high-temperature environments.
5.Machinability: Stellite 6B alloy has excellent machinability, and various parts can be manufactured by cutting, drilling, stamping, grinding, and other methods.
