Ste6
Cobalt-based Ste6 powder for PTA welding thick overlays with wear, galling and heat resistance on valves, seats and heavy-duty parts.
Thick, robust PTA overlay for heavy-duty service
Good resistance to wear, galling and heat
Common option for valve seats and sliding parts
Product description
The PTA version of Ste6 is a cobalt-chrome-tungsten alloy (equivalent to Stellite 6) supplied by Huayin for plasma-transferred-arc hardfacing. Chromium carbides in the cobalt matrix give metal-to-metal wear and galling resistance and retain hardness at high temperature, key properties for valve seats and heavy-duty parts.
PTA welding allows thick, robust cobalt overlays in one or more passes, suiting valve seats, agitator blades, screw conveyors, sliding surfaces and cutters in industrial maintenance. Plasma parameters and powder feed must be set for the required thickness and dilution; CQ distributes Huayin powder with process advice.
Used for valve seats, agitator blades, screw conveyors, sliding surfaces, cutters and parts needing thick cobalt overlays for industrial wear service.
