Interpipe NTRP has completed certification process of Deutsche Bahn for wheels intended for the passenger high-speed trains in accordance with EN 13262.
The new products were mastered in 2016 after putting in operation new facilities for finish operations and high level of geometry control. The mill’s facility for non-destructive testing was approved for detection of 1 mm diameter artificial defects as well. In 2017 the company accomplished the last stage and received successful results of tests, including fatigue one, passed at Deutsche Bahn laboratory.
Mastering of wheel production was preceded by the optimization of the chemical composition and heat-treatments modes as well as implementation of the comprehensive program aimed to improve quality of transport steel production at Interpipe Steel. As a result, wheels of Category 1 steel have better clearness (low level of non-metallic inclusions) and microstructure.
