High manganese steel fittings are mainly used to withstand harsh working conditions such as impact, extrusion and material wear. The damage form is mainly wear consumption, and some parts are broken and deformed. There are three kinds of wear: friction and wear in which the surfaces of metal components contact each other and move; Abrasive wear caused by other metallic or non-metallic materials striking the metal surface and erosion wear caused by the contact between flowing gas or liquid and metal. The wear resistance of low alloy wear-resistant cast steel depends on the material itself, while the wear-resistant steel shows different wear resistance under different working conditions. Only the material itself and working conditions can determine its wear resistance.
Cast wear-resistant steel and wear-resistant steel are mainly austenitic manganese steel. Under certain conditions, low-alloy steel with appropriate heat treatment also has good effect, while graphite steel is used to lubricate the working conditions of friction.
Wear resistant high manganese steel is especially suitable for impact abrasive wear and high stress grinding abrasive wear. It is often used to manufacture impact and wear resistant castings such as ball mill lining plate, hammer head of hammer crusher, jaw plate of jaw crusher, rolling mortar wall and crushing wall of cone crusher, bucket teeth and wall of excavator, railway turnout, tractor and track shoe of tank. High manganese steel is also used for: bulletproof steel plate, safe steel plate, etc.
High manganese steel, alloy high manganese steel and high and medium carbon alloy are used to produce a series of products such as ball mill lining plate, compartment plate, grate plate, crusher hammer head, jaw plate, crusher composite hammer head and plate hammer. The products are widely used in various industries such as mining, smelting, construction, highway, railway, water conservancy and chemical industry.
