Manganese Steel Castings
|
| |
|
This is a unique alloy with high toughness, ductility,
high work hardening capacity, non magnetic in nature and
usually good resistance to wear. Manganese Steel's
ability of work hardening is unique and probably has no
equal in this respect. manganese Steel is used
extensively in field of Mining, Cement, Earthmoving,
Mineral Processing, Oil Well Drilling, Railroading and
Power Sector. |
