Cobalt Alloy Stellite 1 UNS R30001


Short Introduction:

HY S1/Stellite 1/UNS R30001/ AWS A5.21 is a hardfacing alloy that possesses excellent abrasion and corrosion resistance. Stellite 1 keeps its hardness at temperatures above 760C (1400F).

This material contains a high proportion of hard, wear resistant primary carbides. This alloy is well suited to applications involving extreme low=angle erosion and severe abrasion. Stellite 1 is more crack sensitive than the other Stellite grades. One should be careful to minimize the cooling stresses experienced during casting and hardfacing processing.
