Stellite 1 Welding Hard Facing Electrode Cobalt Based Alloy Oil Drilling Tools Rotary Ring
Stellite 1 Welding Electrode - Cobalt Based Alloy Hard Facing Electrode Oil Drilling Tools Rotary Ring
WL-Co1 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).
WL-Co1 contains a high proportion of hard, wear resistant primary carbides. These render the alloy well suited to applications involving extreme low-angle erosion and severe abrasion, with some sacrifice in toughness. Compared to other WL-Co alloys it is more crack-sensitive, and care should be taken to minimize the cooling stresses experienced during casting and hardfacing processes. Due to its high hardness and wear resistance, WL-Co1 should only be finished by grinding.
