DIN 17175 Seamless Tubes
DIN 17175 seamless tubes are used in boiler installations, high-pressure pipelines and tank construction and special machinery for both high temperature and high-pressure devices.
DIN 17175 alloy steel pipe is just a big class,and it has many classifivations. We mainly produce DIN 17175 ST35.8, DIN 17175 ST45.8, and 10CrMo910 steel pipes. These seamless steel tubes are just a big class,and it has many classifivations.
We mainly produce DIN 17175 ST35.8, DIN 17175 ST45.8, and 10CrMo910 steel pipes.
