About AISI/SAE 15xx high-manganese carbon steels
15xx grades are plain-carbon steels with manganese above the standard 10xx range. The extra manganese improves hardenability and impact toughness over plain 10xx grades. Common applications are forgings, axles, and structural shapes where slightly better through-hardening is needed.
