Manganese steel

Steel is a high strength abrasion resistant steel, mainly for the need to withstand impact, extrusion and abrasion of material adverse conditions, the main failure mode to wear, fracture and deformation. The wear is divided into three types: the friction and wear between the contact surface of the metal component and movement; abrasive wear and erosion of flowing gas or liquid and metal contact wear caused by other metal or non-metal materials against the metal surface. The wear resistance of wear resistant steel depends on the material itself, and the wear resistant steel shows different wear resistance under different working conditions.

　　Cast steel and wear resistant steel with austenitic manganese steel, low alloy steel under certain conditions after proper heat treatment also has very good effect, graphite steel is used to lubricate the friction conditions.

　　Wear resistance of high manganese steel is especially suitable for high impact abrasive wear and abrasive wear conditions of force should be crushed, commonly used in the manufacture of ball mill liner, hammer crusher, jaw crusher plate, cone crusher rolling mortar wall and the crushing wall, bucket teeth of excavator, bucket wall, railway turnout, casting tractor and tank track plate impact resistance, abrasion resistance. High manganese steel is also used: armor plate, insurance box plate.

　　High manganese steel is typical of wear resistant steel, cast microstructure is austenite and carbide. After 1000 degrees C, the microstructure transformed into a single austenite or austenite with a small amount of carbide, but the toughness was improved.
