RESEARCH IN FORMING TECHNOLOGY AND HEAT TREATMENT TO IMPROVE POSSIBILITIES TO WORK FOR HAMMER FROM HIGH MANGANESE STEEL

Abstract

High manganese austenitic steel is widely used as parts to withstand impact and abrasion loads in the quarrying, ore industries, etc. The research to improve quality and reduce costs thanks to the application of advanced casting technologies is becoming increasingly important.  development direction of this steel line.  The improvement of steel quality has been proven by world scientists, but steel casting technology is not easy and needs researching. The article introduces some research results of casting technology in glass-sand-water mold for steel hammer details.  The results show that the given casting technology and heat treatment regime have improved the quality of Mn13 steel and ensured the mechanical properties of the details.The mechanical property value obtained after applying the heat treatment regime is the impact toughness reaching 121J/cm2;  hardness value is 260HB; The strength limit is 586Mpa and the elongation is 24.5%, which is in the working condition well.
