DETAILS

Manganese steel is a kind of high-strength anti-wear steel, mainly used for the need to withstand the impact, extrusion, material wear and other harsh working conditions, the main form of wear and tear damage to consumption, part of the fracture, deformation.
Casting wear-resistant steel and wear-resistant steel Austenitic manganese steel-based, under certain conditions by the appropriate heat treatment of low alloy steels also have a good effect, graphite steel is used to lubricate the friction conditions.
Wear-resistant high manganese steel is particularly suitable for impact abrasive wear and high-stress milling abrasive wear conditions, commonly used in the manufacture of ball mill liner, hammer crusher hammer, jaw crusher jaw crushing cone mill crushing wall Walls, excavator bucket teeth, bucket walls, iron turnouts, tractor and tank shoes and other impact, wear-resistant castings. High manganese steel is also used: bullet-proof steel, safe steel plate.
High manganese steel is a typical anti-wear steel, as-cast austenite plus carbides. After about 1000 ° C water quenching the organization transformed into a single austenite or austenite plus a small amount of carbide, toughness but increased, so called water toughening.
High manganese steel is the most important feature in the strong impact, extrusion conditions, the rapid occurrence of surface hardening process, so that the heart still maintain austenite good toughness and plasticity at the same time hardening layer has good wear resistance. This is beyond the reach of other materials. However, the wear resistance of high manganese steel is only sufficient to form a work hardening under the conditions showed its superiority, in other cases is poor.
The typical Mn17 wear-resistant high-manganese steel is based on Mn13 increased manganese manganese, increased austenite stability, prevent the precipitation of carbide, which can improve the strength and plasticity of steel and improve the work hardening ability of steel And wear resistance. For example, the service life of ZGMn18 rail for the north is 20% ~ 25% higher than ZGMn13.
