We will offer high quality DIN 17175 St35.8 seamless boiler tubes and competitive price of DIN 17175 St35.8 boiler tubes. DIN17175 St35.8 seamless steel tube is used for high pressure boiler (working pressure generally above 9.8 Mpa, working temperature between 450 ℃ ~ 650 ℃) of the heating surface pipe, economizer, superheater, reheater tube, petrochemical industry.
DIN 17175 St 35-8 Tubes, are low-cost Low Carbon Steel Tubes with max 017 % carbon content with combination of 040-080 % manganese easy to form and shape.These pipes are manufactured as per DIN Specification and commercially referred as cs pipes or ms pipes. DIN 17175 St 35-8 Carbon Steel Pipes are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.
