ASTM A128 / A128M-1998 for High Manganese Cast Steel
High manganese steel is the carbon content of
0.9% to 1.3%, manganese content of 11.0% to 14.0% of the cast steel,
and it has good toughness and wears resistance. High manganese
steel castings are widely
used in the engineering machinery and, mining machinery etc
This is American ASTM A128 standard and UNS system of
austenitic high manganese
cast steel.
