S355G8+N steel plate introduction: S355G8+N steel plate belongs to marine structural steel plate, implementing EN10025 standard. It can be used to manufacture bridge equipment, marine platforms, derricks, leg piles, pillars, ship equipment, cross-sea bridge structures, port machinery, etc. S355G8+N steel plate has the properties of high strength, high toughness, fatigue resistance, impact resistance, corrosion resistance, wear-resistant welding and easy processing.
S355G8+N steel plate chemical composition:
Carbon (C): maximum 0.18% Silicon (Si): maximum 0.50% Manganese (Mn): 1.20-1.60% Phosphorus (P): maximum 0.025% Sulfur (S): maximum 0.020% Chromium (Cr): maximum 0.30% Nickel (Ni): maximum 0.30% Molybdenum (Mo): maximum 0.10%
S355G8+N steel plate tensile yield strength:
Yield strength: minimum 355 MPa
Tensile strength: 490-620 MPa
Elongation at break: 22% (at 50mm measurement length)
Impact toughness: -20°C minimum 27 Joule (J)
S355G8+N steel plate can be used in the manufacture of drilling platforms, oil and gas field construction equipment, etc., so the requirements of offshore engineering steel not only has a high strength and high plasticity, good welding performance and resistance to seawater erosion, should also have good toughness to ensure that the steel and equipment can adapt to a variety of loads and low temperature environment.
