metallurgies includes Manganese, Low Chrome, Medium Chrome, High Chrome, Martensitic and Composite Ceramic. As shown in the
figure, an increase in the steel's wear resistance (hardness) is usually accompanied by a reduction in toughness (impact
resistance) of the material.
MANGANESE STEEL
The wear resistance of manganese steel with austenitic structure is attributable to the phenmenon of work hardening. The impact and pressure load results in a hardening of the austenitic structure on the surface. The initial hardness of manganese steel is approx. 20 HRC. The impact strength is approx. 250J/cm².
