Introduction of S355G10+N steel plate

1. Introduction of S355G10+N steel plate:
S355G10+N steel plate belongs to weldable structural steel for fixed coastal structures. It is European grade, and its delivery state is normalized or normalized rolled, impacte at -40°C, and 10 after G represents the relevant figures of the characteristics of the steel grade. The +N behind it means normalizing or normalizing rolling.

2. S355G10+N steel plate implementation technical standard: EN10225-2009.

3. Smelting analysis of chemical composition of S355G10+N steel plate:

Grade C Mn P S Cr Mo Ni Cu N Nb Ti V Al Si
S355G10+N 0.12 1.65 0.015 0.005 0.2 0.08 0.7 0.3 0.01 0.03 0.025 0.06 0.015-0.055 0.15-0.55

Among them: Nb+V≤0.06; Nb+V+Ti≤0.08
4. Mechanical properties of S355G10+N steel plate:

Tensile strength MPa Lower yield strength MPa corresponding to thickness (mm) Elongation A% Impact energy
t≤100mm t>100mm ≤16 16-25 25-40 40-63 63-100 100-150 Temperature ℃ Energy J
