Mn13 / 120Mn12 is the genuine fine-grained 12-14%Mn austenitic manganese steel (Hadfield steel) hot-rolled plate. 12-14% Mn austenitic manganese steel shows an outstanding hardening capacity under stress recognized for a long time. As delivered, Mn13 exhibits a moderate hardness of 180 to 240 HB combined with high ductility and impact energy absorption capacity.

Mn13 / 120Mn12 is the genuine fine-grained 12-14%Mn austenitic manganese steel (Hadfield steel) hot-rolled
plate.
12-14% Mn austenitic manganese steel shows an outstanding hardening capacity under stress recognized for a long
time. As delivered, Mn13 exhibits a moderate hardness of 180 to 240 HB combined with high ductility and
impact energy absorption capacity. When exposed to high pressure or impact loads in service, Mn13 / 120Mn12 work
hardens considerably on its surface up to 600 HB, while remaining not brittle in the bulk.
As a result, Mn13 / 120Mn12 exhibits high resistance to abrasive wear, where external conditions cause extensive work
hardening of the wear component’s surface. Mn13 / 120Mn12 has found many applications in crushing and earthmoving
equipment, in railways and in the shot blasting industry.
The second essential property is that Mn13 / 120Mn12 is a non-magnetic steel
Application
It must be noted that the high-manganese wear-resistant steel must be subjected to severe impact or greater pressure to work harden the surface to show its high wear resistance, otherwise the high-manganese wear-resistant steel is not wear-resistant.
At present, the lining and guard plates of foreign wear-resistant machinery have already eliminated castings, and high-manganese wear-resistant steel Mn13 is used for rolling steel plates. High manganese wear-resistant steel Mn13 rolled steel plate with its excellent wear resistance which widely used in shot blasting machines, ball mills, crushers and other parts prone to strong impact wear. Not only used in shipbuilding, automobiles, machinery, power generation, cement, and mining.but also widely used in high-end users in foreign capital and joint ventures such as coal, and has become the inevitable development trend of the new generation of wear-resistant steel selection.
