Hardfacing

[Valving]

Stellite is the most common hardfacing method as far as I see in the industry.
Which other materials are used for hardfacing?
What about nickel overlay? Any comparison for nickel & stellite ?

Unfortunelly at this moment I am not with my specifications in hand but there are tungsten carbide, hard chrome. Try the site of Praxair to find anything else.

Colmonoy is one surface coating material.

There are many Hard facing materials available depend on service application.

Tungsten carbide is the hardest one. Stellite-6 is commonly used HF material
along with SS 316 in valve trims. Also, HF would be used in High Pressure appln only.
