DIN 17175 is designed for elevated temperature purposes, Bestar Steel supplies following steel grades: St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910. DIN 17175 seamless steel pipes are widely used in heat exchange appliances. The pipes under DIN 17175 are manufactured from carbon and low-alloy steel grades which are resistant to loads under high pressure and temperatures. They are used for the construction of power engineering appliances such as: boilers, heating coils, stoves, heaters, heat exchanger tubes.

DIN 17175 seamless steel pipes are used for boiler installations, high-pressure pipelines and tank construction and special machinery for both high temperature and high-pressure devices(Above 450° high temperature). Bestar Steel is an experienced boiler and pressure steel tube supplier which can offer you DIN 17175 steel pipe of all grade and dimension range.
