Abstract：Austenitic based low density steel is prone to coarse microstructure and component segregation during the production process, which may be detrimental to the friction and wear properties of this type of steel. Based on this, this article studies the impact of friction and wear processes on the friction and wear properties of the steel using vacuum induction melting and electroslag remelting of austenitic based low density steel Mn20Al10 (20% Mn, 10% Al, and 1.5% C, mass fraction) with high Mn, high Al, and high C. The conclusion is as follows: The wear forms of induction melting forged plates and electroslag remelting forged plates are mainly oxidation wear and abrasive wear. The wear under light load and low rotational speed is mainly abrasive wear, and the wear mechanism under heavy load and high rotational speed conditions is transformed into oxidation wear. Under the same friction and wear conditions, the surface layer of electroslag remelting forged plates has a higher content of Al2O3, and the lubrication effect of Al2O3 in the friction and wear process, The work hardening of electroslag remelting forged plate under lower load is significantly higher than that of induction melting forged plate, which makes the wear performance of electroslag remelting forged plate better than that of induction melting forged plate under load of 50~125 N and rotation speed of 100~300 r/min. In addition, with the increase of rotational speed, the wear resistance of induction melting forged plates and electroslag remelting forged plates gradually improves; As the load increases, the wear resistance of induction melting forged plates and electroslag remelting forged plates first increases and then decreases.
