EN S355J0 High Strength Structural Hot Rolled Steel
S355J0 high-strength steel plate is a low-alloy high-strength structural steel with excellent mechanical properties and wide application.
S355J0 high tensile steel sheet implements the European standard EN 10025-2 and is a European standard low-alloy high-strength steel. The "S" in its name stands for structural steel, "355" means that the minimum yield strength of the steel plate is 355MPa, and "J0" means its impact toughness grade, that is, 0-degree impact.
S355J0 high strength steel plate can still maintain good toughness at low temperatures, and is easy to cut, bend, form and other processing operations, meeting the requirements of complex manufacturing processes.
