Product introduction of S355J2H LSAW steel pipe
S355J2H is a European standard material designed specifically for cryogenic applications, and its implementation standard is EN 10210. It is primarily produced in the form of seamless steel tubes and seamless square/rectangular tubes. S355J2H carbon steel tubes are low-alloy, high-strength structural steels with mechanical and weldability properties similar to S355J2G3. Its yield strength is approximately 355 MPa, and its tensile strength ranges from 470 to 630 MPa. Furthermore, it possesses excellent impact toughness and corrosion resistance.
These seamless steel tubes are mainly used in cryogenic climate steel structure engineering, the construction of large stadiums, and the manufacture of cryogenic containers. S355J2H steel tubes are also suitable for offshore oil platform construction. The good machinability of S355J2H carbon steel round tubes makes them an ideal material for manufacturing cryogenic mechanical parts.
