| Valve seat coating
Hi All,
A customer - a power plant wants to protect its valve seat from erosion caused due to high pressure water ( no corrosion as de mineralized water) ; pressure upto 150 kg/cm2. Customer tried stellite 6 welding and failed; my best guess was due to a high HAZ during welding of the small part ; Suggestion on what coating an work? And would any sealer stay at the said pressure? Regards Shantanu | |||
