X120Mn12 (Mn13) is the best choice for high impact resistance and a material with high wear resistance and stress. High manganese steel has two biggest characteristics: firstly, it has greater external impact and higher appearance wear resistance; Another is the continuous formation of new dense lamination processes as the appearance of dense lamination gradually wears away. X120Mn12 (Mn13) forged steel plate has excellent wear resistance to high impact wear and high stress wear, and will not collapse during use. It also has machining mechanical properties such as easy cutting, welding, and bending. High chromium forgings are used, which only have good mobile wear resistance.

Used for vulnerable parts of low-end equipment, saving equipment overhaul costs and improving competitiveness.
11 percent to 14 percent manganese steel with excellent work hardening properties. Suitable for wear applications where high impact/gouging wear results in work hardening effects. X120Mn12 manganese steel plate can be cut by plasma or laser profiling. This product is a non-magnetic, work hardening wear-resistant steel plate, which is provided in the form of whole plate or cutting pieces.
Forming can be carried out without difficulty, as the sheet under supply conditions has ductility. To avoid cracking, edges that have been shear work hardening should be chamfered and ground 2 to 3 mm along the edges to be formed. If possible, forming shall be carried out in one operation to avoid work hardening.
Since the manganese content is 11 percent to 14 percent , high manganese steel is difficult to drill and will soon work hardening. Heavy and very sturdy machinery requires the use of 8 percent cobalt high-speed steel armor piercing drills, or preferably special drills with replaceable hard alloy blades. Avoid center punching or let the drill bit rub on the surface without feeding, because this will produce work hardening effect.
Welding should be carried out using E308Mo type austenitic stainless steel consumables. As a high manganese steel with high coefficient of thermal expansion and low coefficient of thermal conductivity, welding should be carried out under low heat value. Long term storage of materials within the temperature range of 300 degree C to 800 degree C can lead to embrittlement due to carbide precipitation.
