Stellite 1 Powder Polystel 1 ERCoCr-C Hard Facing Powder Gouge Type Bearing Sleeve Drill Head
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.
