...-carbon steel bar, as specified by UNS G10800 (AISI/SAE grade 1080). EDX analysis found 1.1% Mn in the chip, with the balance being iron, and 1.0% Mn in the hammerhead; thus, the chip is a plain carbon steel with a manganese content consistent with that of the head. Composition of sledgehammer head...
