Steeltec company has built innovative finishing line to ensure improved steel characteristics ready to operate at low temperatures (-101 °C). Dynamic ultimate allowable load increases at least by 10 % what has positive effect on service life of loaded components. It allows to increase resistance of already used components or to determine parameters without energy loss. Innovative technology Xtreme Performance (XTP) Technology is the way to provide the aimed temperature procedure before and after deformation with large reduction for section steel. It finalized in forming of extra homogenous fine-grained steel structure with grain size less than 5 μm as a guarantee of very high toughness and dynamic ultimate allowable load.
