EVRAZ ZSMK has completed certification of low temperature-resistant HH350 rail, receiving the relevant certificate from The Federal Railways Certification Register. The head-hardened rail intended for use at low temperatures successfully passed tests at The Russian Rail Transport Research And Development Institute. The certificate opens the way to commercial production and sales of the new rail type within the Customs Union.
The new rail type is intended for cold climates with temperatures going down to minus 60 degrees Centigrade, i.e. in the Northern regions of Russia, in the Far East, in Eastern Siberia. The high damage tolerance at low temperatures increases the service life of rail and brings down the maintenance costs while improving safety. The new rail type is available in lengths from 8 to 100 meters.
It is worth noting that it took EVRAZ engineers just one year to roll out the new technology. Currently The Russian Rail Transport Research And Development Institute is developing the technical specifications for welding the new rail type.
