X120MN12 grade manganese plate & Sheets Supplier in Mumbai-India.
Manganese steel - also known as hard manganese steel or manganese hard steel – in its quenched state has the emblematic 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 persistence. The cold working performed increases the wear-resistance enormously. It can be bent, flanged and pierced because of its high persistence. Chipping at room temperature with hard metal tools is only possible to a limited extent.
Typical use of manganese steel
Hangers in blasting machines,
Crusher jaw inserts
Power shovel bolts
Power shovel connectors
It is used generally for intense percussion and impact stresses.
Manganese steel can be welded both electrically and autogenously. Electrical welding is, however, preferred because with autogenously welding procedures, burn-off of manganese and carbon may easily occur. Shielded electrodes at 0.8% - 1.0% C and 15 - 18% Mn must be used for electric welding. The wear resistance is somewhat lower at the weld seam than with the remaining material.
