Stellite^® 1 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).

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 it's high hardness and wear resistance, Stellite^® 1 should

only be finished by grinding.

Corrosion Resistance

Stellite^® 1 has good general corrosion resistance. The typical electrode potential in sea water at room

temperature is approx.-0.4 V (SCE). Stellite^® 1 corrodes primarily by a pitting machanism ans not by

general mass loss in seawater and chloride solutions. More detailed imformation regarding corrosion

resistance can be provided on request.
