1.1165 | G28Mn6 with hard facing

Numeric designation1.1165
Chemical designationG28Mn6
Statehard facing
Etching3 % Nital

Carbide-rich hard facing (18% Cr, 6% Nb) on a excavator bucket of 1.1165. The microstructure contains NbC and M7C3 primary carbides in M7C3 austenite eutectic. A soft interlayer has been omitted, and the lighter zone on the right (perhaps an arc strike) is merely remelted and finely solidified. The cracks in the hard facing do not continue into the base metal.
