Is DIN 17175 ST35 8 steel pipe equivalent to ASTM?
DIN 17175 ST 35.8 is equivalent to ASTM A179. Both standards specify seamless carbon steel tubes for use in heat exchangers and condensers.
DIN 17175 St 35-8 grade carbon steel seamless pipe is also known as mild steel pipe. DIN 17175 grade St 35-8 pipe is a low-cost low carbon steel pipe with a maximum carbon content of 017% and a manganese content of 040-080%.
ST35.8 boiler tube is a kind of seamless steel tube for low and medium pressure boilers. Made of carbon structural steel, the implementation standard is DIN171751. This type of steel pipe is mainly used to manufacture heating surface pipes of low and medium pressure boilers, such as water wall pipes, boiling water pipes, superheated steam pipes, etc.
