Manganese steel – also known as hard manganese steel or manganese hard steel – in its quenched state has the characteristic of significantly increasing its original low tensile strength and hardness in the cold-worked layer by intense cold working without this having an adverse effect on the originally very high durability. The cold working performed increases the wear resistance enormously. It can be bent, flanged, and pierced because of its high durability. Chipping at room temperature with hard metal tools is only possible to a limited extent.
X120Mn12 is a kind of high manganese wear-resistant steel material, which is the best choice for resisting high impacts, high pressures among wear-resistant steels. The features of X120Mn12 steel plates: 1. The heavier the impacts from outside to the surface of steel plates, the higher performance of abrasive resistance from the surface of steel plates will have. 2. With the abrasion of the hardening layer of X120Mn12 steel plates, more new hardening layers will be taken shape continually. X120Mn12 hot rolled steel plates have excellent properties in resisting strong impacts abrasion and high-stress abrasion. Besides, X120Mn12 steel plates won’t be crushed when in the application and are easy to be cut, welded, and bent when taking mechanical machining works.

Typical manganese steel products are, for example, hangers in blasting machines,
crusher jaw inserts,
power shovel bolts,
power shovel connectors,
striking elements in impact mills and centrifugal mills.
It is also used in security systems (protective grills, doors, cladding, safety plates). It is used generally for intense percussion and impact stresses.
