High manganese steel is a traditional wear-resistant steel, thecompany's large-scale application. This paper analyzes the impact of highmanganese steel and the relationship between work, high manganese steeland low alloy steel in different impact energy of wear resistance, highmanganese steel for discrimination based on work hardening occurred.Further analysis of high manganese steel company I work situation, find outfrom the actual conditions improve wear characteristics, Productioncompanies solve practical problems.High manganese steel suitable condition is work-hardening valuegreater than HRC54 high stress (or high-impact energy), the abrasive wear.Work hardening in the value of less than HRC45 conditions, In no otherhigh manganese steel optimization of the low-alloy steel to be elected aswear pieces.Against the use of the company mill liner short cycle, often broken,such as pipe casting problems. I used to Minnie re-high manganese steelalloys, and to improve the wear resistance of the melting after blowingnitrogen use, refined, Casting improve quality.The wear resistance of high manganese steel is mainly because of itsability to work hardening, so We modified the design of high manganesesteel hammer and hammer the chemical composition, a sense joined thechromium (Cr) Molybdenum (Mo), titanium (Ti), vanadium (V) and RE,reducing the stability of austenite, it matrix formed many small particles ofthe second phase, to prevent dislocation movement, thereby strengtheningthe matrix.Austenitic and it diffuses the globular carbide precipitation,purification grain boundaries, improve the shape of inclusions anddistribution, strengthen the comprehensive realization that it will have hightoughness and high strength and good wear resistance.
