Milestone Co6 TIG is a general‑purpose cobalt‑chromium‑tungsten TIG hardfacing welding wire, complying with AWS A5.21 ERCoCr‑A (equivalent to Stellite 6). It is designed for high‑temperature, abrasive, corrosive and impact‑loading conditions.
-
Hardness: HRC 40–46
-
Heat resistance: stable performance up to 800°C
-
Properties: excellent wear resistance, impact resistance, anti‑galling, cavitation resistance & high temp corrosion resistance
-
Process: DC TIG welding, stable arc, smooth bead, low spatter, low dilution, good machinability
-
Applications: valve seats, engine valves, turbine blades, pump shafts, hot shear blades, forging dies, extruder screws, mining wear parts
Application:
Suitable for welding 06Cr17Ni12Mo2 stainless steel equipment operating in organic and inorganic acid (non-oxidizing acid) media. It can also be used for welding high-chromium steels that cannot undergo post-weld heat treatment or for dissimilar steel joints.
