S355J2W+N Corten Steel, also known as Corten Steel or Corten steel, is a low-alloy, high-strength structural steel with excellent weather resistance. It belongs to the EN 10025-5 standard material, widely used in construction, Bridges, vehicles and ships, especially for structures that need to be exposed to harsh weather conditions for a long time.
S355J2W+N Corten Steel features
Weather resistance: S355J2W+N has excellent weather resistance, can maintain long-term stable performance under harsh environmental conditions such as high humidity and high salt, and is not easy to rust and corrosion.
High strength: This steel has high yield strength and tensile strength, which can meet the strength requirements of various structural parts.
Good plasticity and toughness: it can maintain good deformation ability when stressed, thereby improving the safety of the structure.
The main chemical components of S355J2W+N Corten Steel include:
Carbon (C) : ≤0.19%
Silicon (Si) : 0.30-0.65%
Manganese (Mn) : 0.80-1.25%
Phosphorus (P) : ≤0.040%
Sulfur (S) : ≤0.050%
Chromium (Cr) : 0.40-0.65%
Nickel (Ni) : ≤0.50%
Copper (Cu) : 0.25-0.40%
In addition, it may also contain a small amount of vanadium (V), molybdenum (Mo) and other elements to further improve the weatherability and corrosion resistance of the steel.
The mechanical properties of S355J2W+N Corten Steel mainly include:
Yield strength: not less than 355MPa, which ensures that the steel is not easy to deformation or damage under pressure.
Tensile strength: between 450-680MPa, showing the high strength characteristics of steel in the tensile state.
Elongation: between 18-28%, reflecting the ductility of the steel when subjected to external force.
