S355J2G3大致相当于GB的Q345D。
St. 52-3 N (1.0570) ? S355J2G3
S: Structural Steal
J2: 27 Joule for testing temp -20 DegC (Nom. Thick. >10 / <=150 mm)
G3: Normalised
Yield ReH: 275 ? 355 MPa
Tensile Rm: 450 ? 680 MPa
Lowest values are for the lowest value of the thickest section available.
Heist values are for the heist value of the thinnest section (<3 mm for Rm, <=16 mm for ReH)
