What is Manganese Steel?

Manganese steel, commonly known as Hadfield steel or high manganese steel, is a unique non-magnetic alloy that possesses an extraordinary ability to harden under impact. Unlike conventional structural steels, this material thrives in the most punishing industrial environments. It is the ultimate choice for applications requiring high impact resistance combined with substantial abrasion resistance. 

First developed by Sir Robert Hadfield in 1882, this alloy typically contains 12-14% manganese and 1.0-1.4% carbon. Its defining characteristic is its work-hardening capability. When the surface of manganese steel is subjected to intense impact or compression, it undergoes a phase transformation that significantly increases its surface hardness while maintaining a ductile, tough core. This prevents catastrophic failure, making it indispensable for crusher wear parts steel, mining equipment, and railway components. 

For engineers and procurement professionals seeking manganese steel suppliers, understanding the specific grades—such as X120Mn12 steel (EN 1.3401) or ASTM A128 manganese steel—is critical. Selecting the right grade ensures your equipment can withstand the severe shock loading found in quarries, mines, and recycling plants.
