DIN 17175 Material Comparison Tables

DIN 17175 steel pipes are used in boiler installations, high-pressure pipelines and tank construction and special machinery for both high (градусов 600) temperature and high-pressure devices.

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.

Application:

used for the pipelines of boiler industry.
