It is designed for use in various structural applications where high strength and corrosion resistance are required. This steel plate offers a combination of mechanical properties and welding performance, making it suitable for a wide range of industries.
Chemical Composition
The chemical composition of S355J2G3 steel plate is carefully controlled to ensure its excellent mechanical properties and corrosion resistance. The main chemical elements include: Carbon (C) ≤ 0.20%, Silicon (Si) ≤ 0.55%, Manganese (Mn) ≤ 1.60%, Phosphorus (P) ≤ 0.035%, and Sulfur (S) ≤ 0.035%. Additionally, it may contain trace amounts of alloying elements such as Chromium (Cr), Nickel (Ni), Vanadium (V), Copper (Cu), and Titanium (Ti), which further enhance the steel's performance.
Mechanical Properties
S355J2G3 steel plate exhibits impressive mechanical properties, including a tensile strength (Rm) ranging from 355 MPa to 510 MPa, depending on the plate thickness and heat treatment state. The yield strength (Re) is 345 MPa, and the elongation (A) is ≥22%, indicating good plastic deformation ability during tensile testing. The impact energy (KV) at -20°C is greater than 27J, demonstrating the steel's toughness at low temperatures.
Heat Treatment State
S355J2G3 steel plate is typically delivered in the normalized condition, which improves its mechanical properties and processing performance. However, it can also be subjected to other heat treatments or processing according to customer requirements, such as hot rolling, controlled rolling, thermomechanical controlled processing (TMCP), or annealing.
Low-Temperature Impact Test
The low-temperature impact test ensures that S355J2G3 steel plate maintains sufficient toughness at low temperatures. The steel plate has an impact absorption energy requirement of at least 27J at -20°C, ensuring it can withstand impact loads without fracture in cold environments.
Producible Size Range
S355J2G3 steel plate is available in a wide range of sizes to meet different application needs. The thickness can vary, with common sizes including 6-50mm for medium plates and thicker plates up to 400mm available upon request. The width typically ranges from 1000-4000mm, and the length can be customized according to customer specifications.
