Stellite 1 possesses 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).
Stellite 1 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 Stellite 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, Stellite 1 should only be finished by grinding.
