 MN13 steel is mainly used to need to withstand impact, extrusion, material abrasion and other harsh working conditions, wear and tear damage to form the main part of the fracture and deformation. Wear is divided into three types: mutual contact between the surface of metal components and movement of friction and wear; other metal or non-metallic materials against abrasive wear of metal surfaces and flow of gas or liquid contact with the metal caused by erosion. Abrasion wear resistance of steel depends on the material itself, while the wear of steel in different working conditions show different wear resistance, the material itself and working conditions between the two in order to determine their wear resistance. ???? Steel and wear resistant cast austenitic manganese steel in the main, under certain conditions the low alloy steel with appropriate heat treatment has good results, graphite steel is used for lubrication of the working conditions of friction ????? wear especially for the impact of high manganese steel and high-stress abrasive wear crushed abrasive wear condition, commonly used in the manufacture of ball mill liner, hammer hammer crusher, jaw crusher jaw plate, cone crusher rolling acetabular wall, broken walls, excavator bucket teeth, bucket wall, railway turnouts, crawler tractors and tanks board impact, wear resistant castings. High-manganese steel is also used: bullet-proof steel, safe plate and so on. ?? High-manganese steel is a typical anti-wear steel, cast structure of austenite plus carbide. After about 1000 ° C water quenched? Treatment organization into a single austenite or austenite plus a small amount of carbide, but to improve toughness, so called tough water treatment. ???? High-manganese steel of the most important feature is the strong impact, extrusion conditions, the surface hardening rapidly, so that the Department of mind remains austenitic good toughness and ductility, while hard? Layer with good wear resistance. This is less than the other materials. However, the wear resistance of high-manganese steel have enough to form only in the hardening conditions to demonstrate its advantages, other cases are poor.

 Material Name: Impact of high-manganese steel 
 Grade: Mn13 
 Standard: WKJ09-008 
 ● Mn13 Features and Scope: 
 Mn13 is a high wear-resistant manganese steel (HIGH MANGANESE STELL SCRAP) is a strong resistance to impact, abrasion and other wear-resistant materials, a large stress in the material the best choice. The greatest feature of high-manganese steel are two: First, the greater the external shocks, the higher the wear resistance of its own surface; Second, with the gradual wear of the surface hardened layer, the new work-hardening layer is continuously formed. Mn13 rolled steel plate for strong shocks and high stress abrasion wear has an excellent wear resistance, in the course will not be broken, but with the ease of cutting, welding, bending and so easy machining properties. Traditional use of high-contact cast is just wear and tear on the mobile better wear resistance. Mn13 steel rolling equipment can reduce the use of wearing parts and save the cost of equipment maintenance costs, improve product competitiveness.
