Austenitic Manganese Steel Castings

Austenitic manganese steel, containing about 1.2% C and 12% Mn, was invented by Sir Robert Hadfield in 1882. Hadfield's steel was unique therein it combined high toughness and ductility with high work-hardening capacity and, usually, good resistance to wear it rapidly gained acceptance as a really useful engineering material.

Austenitic Manganese Steel Applications:
Hadfield's austenitic austenitic manganese steel is still used extensively, with minor modifications in composition and heat treatment, primarily within the fields of earthmoving, mining, quarrying, oiler drilling, steelmaking, railroading, dredging, lumbering, and within the manufacture of cement and clay products.

Austenitic austenitic manganese steel is used in equipment for handling and processing earthen materials (such as rock crushers, grinding mills, dredge buckets, excavator buckets and teeth, and pumps for handling gravel and rocks).

Other applications include fragmentizer hammers and grates for automobile recycling and military applications like tank track pads.

Another important use is in railway trackwork at frogs and crossings, switches where wheel impacts at intersections are especially severe.

Because austenitic austenitic manganese steel resists metal-to-metal wear, it's used in sprockets, pinions, gears, wheels, conveyor chains, wear plates, and shoes.
