What material is S355J0 steel pipe made of?
S355J0 is a non-alloy European standard steel commonly used to manufacture structural parts. Its standard number is EN10025-2. Its chemical composition includes content of elements such as carbon, silicon, manganese, phosphorus and sulfur. S355J0 steel plate has high tensile strength and impact toughness, as well as good weldability and processability. This steel plate can be used in the manufacture of important structural parts such as bridges, cranes, and buildings.
S355J0 spiral steel pipe has excellent mechanical properties, and its tensile strength, yield strength, elongation and impact energy are all high. Among them, the tensile strength can reach more than 590MPa, the yield strength can reach more than 490MPa, the elongation can reach more than 18%, and the impact energy can reach more than 100kJ/m2.
