DIN 17175 seamless steel pipe is used in boiler installations, high-pressure pipelines and tank construction and special machinery for both high temperature and high-pressure devices. And it is widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automobile transmission shaft, self frame as well as the construction of the steel scaffolding.
Steel Grade: St37, St44, St45, St52, 15Mo3, 13CrMo44, 10CrMo910, 14MoV63,
