HIGH-GRADE steel designed to reduce damage from rolling contact fatigue has been selected for wheels being supplied by Lucchini Sidermeccanica.
Branded as Superlos grade, the steel is a pearlitic silicon and manganese carbon mix which the supplier says is well-suited to a low-temperature environment.
Lucchini’s contract is in two parts. One covers wheels for the three complete and seven ckd trainsets being built by Alstom at Savigliano. The other is for those assembled by CRC in Changchun. For this part of the contract Lucchini will provide finished Superlos wheels and semi-finished Uplos axles. n
