Manganese Steel Casting
Hadfield's austenitic manganese steel (11–14% Mn) is the go-to material for parts subjected to heavy impact and abrasive wear. These castings self-harden on impact, becoming harder with use while retaining core toughness.
We produce manganese steel castings conforming to IS 276 and ASTM A128 standards. The castings undergo solution annealing treatment to achieve the optimal austenitic microstructure. Key applications include crusher jaws, blow bars, liners, and swing hammers used in mining, cement, and quarrying industries.
Key Features
- Manganese content: 11–14% (Hadfield's grade)
- Self-hardening on impact – work hardens from ~200 BHN to ~550 BHN in service
- Solution annealing heat treatment for optimal austenitic structure
- High impact toughness even at sub-zero temperatures
- Capacity: 20 kg to 2,500 kg per piece
Applications
Crusher Jaws & Cheek Plates
Blow Bars (Impact Crushers)
Liners & Mantles
Cement Plant Components
Mining Equipment
Railway Crossings & Frogs
