introduction
S355J2H steel pipe has excellent mechanical properties, with a minimum yield point of 355MPa, a minimum tensile strength of 510-680MPa, a minimum elongation of 22%, and a maximum strip shrinkage of 30%. These mechanical property parameters are relatively high, indicating that this low-alloy structural steel can withstand large mechanical loads, has good toughness under bending, impact, etc., and can also resist stress corrosion cracking in high or low temperature environments.
The excellent performance of S355J2H spiral steel pipe comes from the comprehensive effect of hot rolling process, high-quality raw materials, advanced steel production technology and other factors. Therefore, when manufacturing pressure vessels, transportation pipelines and various engineering machinery, choosing S355J2H low alloy steel pipe can not only ensure the mechanical strength and toughness of the workpiece, but also extend the service life and improve work efficiency.
S355J2H spiral welded pipe has excellent mechanical properties, high strength, plasticity, weldability and corrosion resistance, and is widely used in various manufacturing fields.
