• Idrha+ produces hardened rails with improved resistance to contact fatigue and wear
• System was developed by Siemens and RINA-CSM
Siemens Metals Technologies has received notice from Baotou Iron & Steel (Group) Co. Ltd. that the in-line “Injector Dual-phase Rail Hardening” (Idrha+) achieved the expected performances for the rail R60 U75V gr.340 according to TB/T2344-2012 norm and has therefore entered the regular commercial production. The system, contracted to Siemens in December 2012, is capable to improve the rail resistance to both wear and rolling contact fatigue, and was designed by Siemens Metals Technologies and Centro Sviluppo Materiali S.p.A. (RINA-CSM).
