S275JR S355JR Hot dip galvanized pipe for compressed air

S275JR and S355JR hot-dip galvanized pipes are two commonly used steels. They are treated with hot-dip galvanizing and have good corrosion resistance and long service life. They are particularly suitable for occasions that need to withstand industrial fluid media such as compressed air.
S275JR steel pipe belongs to the European standard low-alloy high-strength structural steel pipe, and the implementation standard is EN10025. Its chemical composition includes a carbon content of about 0.23%, a manganese content of about 1.5%, a silicon content of about 0.4%, a phosphorus content of about 0.04%, and a sulfur content of about 0.05%. It is widely used in structural engineering, vehicle manufacturing, storage tanks and containers, steel structure buildings, and infrastructure engineering.
S355JR is similar to S275JR, and is also a low-alloy high-strength structural steel pipe that implements the same EN10025 standard. Its chemical composition and mechanical properties are similar to those of S275JR, and it also has excellent mechanical properties and weldability, which is suitable for various engineering and construction applications.
