In view of the particularity in the material for the diesel engine`s high-pressure fube, we adopt the high-quality carbon steel tube bland from the BaoSterel, with the desination codes being St35, St35.8, St37, St37.4, St45, St55 which are superior to the fube billets of other rfademarks in terms of such mechanical properties such as the elongation percentage, tensile strength and especially high pressure resistance.
