High Manganese Castings

ASTM A128 Grade D manganese steel, designated UNS J91459, is known for its high toughness, ductility, and excellent wear resistance. It is a high manganese austenitic steel that is often used in high-wear applications where durability and longevity are crucial. The steel's unique properties arise from its high manganese content, which significantly improves its hardness and wear resistance under high impact conditions
