Description
Austenitic Mn-steel. The well-known Hadfield steel still has broad applications in the mineral processing industry. Especially under impact loading Hadfield steel displays good wear resistance due to its high cold work ability. However, Hadfield steel is not corrosion resistant.

Applications
Components for dredgers and crushers, conveying machines: crushing jaws, impact wedges, linings and more.

Physical properties (average values) at ambient temperature
Modulus of elasticity [10³x N/mm²]: 190-210
Density [g/cm³]: 7.88

Hardening
Harden from a temperature of 1000-1050^oC followed by water quenching. Hardness after quenching is about 200 HB.

Mechanical properties at ambient temperature:
0.2 % proof stress (N/mm²): 350
Tensile strength (N/mm²): 800-1000

Forging
Hot forming temperature: 1050-850^oC

Machinability
The machinability of this steel is poor.
