IDENTIFICATION
GM ST-12, ER CCoCr-B

CLASSIFICATION
AWS/SFA 5.21: ER CCOCR-B

DESCRIPTION
GM ST12 content of complex carbides in an alloy matrix. They are resistant to wear & corrosion to retain these properties at high temperature. These wear resistance in mainly due to inherent characteristic of hard carbide phase.
