Cobalt Based Alloy Powder Stellite 1 Hardfacing Welding Powder for Valve Seats
Product Description
WLCo-1 is a cobalt based welding powder that has the highest hardness and wear resistance of the standard cobalt alloys. WLCo-1 is used in elevated temperature, high wear applications. Exceptional resistance to metal-to-metal wear in corrosive media at high temperatures. It is a hardfacing alloy possessing excellent abrasion and corrosion resistance for applications such as pump sleeves, rotary seal rings, wear pads, expeller screws and bearing sleeves. It retains its hardness at temperatures in excess of 760°C (1400°F).
