ASTM A128 Standard is a standard specification for high manganese steel castings, which is suitable for the manufacture of various types of high manganese steel castings, including lining plate for gravel breaker, jaw plate for jaw crusher, hammer head for hammer crusher, etc. These castings usually need to be wear, impact, and wear resistant to meet the requirements for use in mining, construction, and other industrial {{II}} agros

In addition to the chemical composition and mechanical properties, the ASTM A128 standards also set forth the requirements for the heat treatment process and surface quality of high-manganese steel castings. Heat treatment process can improve the organizational structure and performance of the casting, and improve its wear resistance and impact resistance. The requirements for the surface quality include the surface roughness, defects and oxide layer to ensure that the casting can maintain a Bonum superficies conditio in usum {{IV}}
