Manganese Steel

Manganese Steel Plate and Bars

11% to 14% Manganese Steel that performs best in extreme impact applications. Under shock and impact it nearly triples its initial surface hardness, retains its interior toughness and acquires a high polish. These features, combined with manganese steel high tensile strength, make it an ideal material for heavy impact and abrasive services. Manganese Steel is also non-magnetic.

Our manganese steel applicator bars help prolong the life of Rock Crusher Hammers, Jaws, Mantles, and others subjected to severe impact. Metal-on-Metal applications, such as pins in drag lines and shovel buckets, provide excellent use of manganese bars.
