Description of SIDUR 3401 Plates :
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 of SIDUR 3401 Plates :
Components for dredgers and crushers, conveying machines: crushing’s jaws, impact wedges, linings, etc.
Hardening of SIDUR 3401 Plates :
Harden from a temperature of 1000-1050 Degree C followed by water quenching. Hardness after quenching is about 200 HB
Forging of SIDUR 3401 Plates :
Hot forming temperature: 1050-850 Degree C
Machinability of SIDUR 3401 Plates :
The machinability of this steel is poor
