Austenitic manganese steel, also called High manganese steel, is a kind steel that commonly used for wear-resistant steel in machinery industry, these wear parts usually have excellent performance: high strength, high toughness,high wear resistance, but the machinability of high manganese steel is poor,it mainly has the following difficulties:
(1) Plastic deformation, severe processing har-dening;
(2) Large plasticity, easily to form BUE,
(3) Large cutting force, high toughness, not easy to break.
(4) Due to the large cutting force, the unit cutting power increases, the heat generated per unit time and high manganese steel itself poor thermal conductivity, the cutting zone temperature up to 1000 ℃, severe tool wear, tool life is low.
Common component includes: High Manganese steel Crushing Cone, High Manganese steel liner, high manganese steel roller and high manganese steel guard.
