The requirements of S355J2H:
1: Brand representation method
The steel brand consists of three parts: the Chinese phonetic letter representing the yield strength, the yield strength value, and the quality grade symbol, for example:
S355J2H. Among them: the steel starting with S is structural steel, 355—yield strength value, unit MPa; and the steel starting with S is carbon steel, so you only need to find a domestic brand carbon steel with a minimum yield strength of 355MPa at room temperature.
2: Implementation standard: EN10210 (cold-bent hollow steel for structure).
3: Chemical composition of S355J2H steel pipe:
C≤0.24; Mn≤1.60; Si≤0.55; P, S≤0.04; N≤0.009
4: Mechanical properties
Tensile strength: 450-630.
Elongation: ≥21.
Impact test: -20℃: ≥34.
5: Smelting method
Steel is smelted by converter or electric furnace, and refining is added outside the furnace when necessary.
6: Delivery status
Steel is delivered in hot rolling, controlled rolling, normalizing, normalizing + tempering, and thermomechanical rolling (TMCP) status.
