Stellite welding is a process of hard-facing utilized heavily in the valve industry. Hardfacing material is applied to the contact surface and moving areas of the valve such as the valve seat, valve plug, to provide wear resistance and corrosion resistance, primarily applied as an overlay for carbon steel, stainless steel and nickel-based alloys.
It will produce a wear and corrosion resistant coating extending the life of the application. Many valves that involve high pressure, high temperature steam require Stellite Welding to withstand their harsh operating environment.
Typical valve applications include:
