PRODUCT DESCRIPTION
Stellite 1 ERCoCr-C POLYSTEL 1 Cobalt Welding Rod Hard Facing Rod Engine Valve Pump
Sleeves

Product Description
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.
