Composition & metallurgy

Classic compositions are roughly 1.0–1.4% carbon with about 11–14% manganese, though proprietary and modified grades vary.

Common grades and standards

Commonly supplied under cast wear-steel specifications such as ASTM A128 grades, with composition selected for casting size and service.

Applications

Crusher jaws and cones, rail crossings, impact hammers, dredging parts, shot-blast equipment and heavy mining wear components.

Engineering characteristics

Relatively soft in solution-treated condition but work-hardens dramatically in service. It is difficult to machine after work hardening and must be welded with appropriate low-heat-input practices.

Known manufacturers and producer regions

Produced by specialized foundries worldwide rather than only large integrated mills. Major mining regions in China, India, South Africa, Europe, Australia and the Americas have manganese-steel foundries and wear-parts manufacturers.

Before specifying or purchasing

Confirm governing standard and edition, product form and dimensions, delivery/heat-treatment condition, mechanical properties, toughness, welding requirements, corrosion or wear environment, inspection/NDT, traceability and mill test certification. Manufacturer capability varies by plant and product line.
