DIN 17175 Heat-resisting seamless steel tube
DIN 17175 seamless steel pipes 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. This 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.
