Mac Hica E3073
AWS Co Cr-B
Descriptions & Applications:
Grade 12 stellite type high recovery cobalt based electrode designed to combat all four elements of wear, i.e. heat, impact, corrosion and abrasion. The electrode provides optimum impact and abrasion resistant properties while retaining hardness at elevated temperatures. Excellent for rebuilding corners with minimum base metal dilution. Has ability to overlay extensive areas without cracking. Welds are non-machinable.
