Corten sheets made from S355J2W steel are commonly used in various applications such as cladding, roofing, and architectural panels. The sheets have a unique rust-like appearance that changes over time due to the exposure to weather elements. The Corten sheets have a higher resistance to atmospheric corrosion than other steels due to the addition of copper, chromium, and nickel. These elements create a protective oxide layer on the surface of the steel, which prevents the steel from corroding further.

The "N" in S355J2W N indicates that the steel has been normalized. S355J2W is a hot-rolled weather-resistant structural steel grade. The "S" in the designation stands for structural steel, while "355" refers to the minimum yield strength value in megapascals (MPa). The "J2W" part indicates that it is designed to have improved atmospheric corrosion resistance, making it suitable for outdoor and exposed environments. The "J2" indicates that the steel has been impact-tested at -20°C, and the "W" signifies its resistance to atmospheric corrosion.

S355J2W is part of the EN 10025-5 standard, which specifies the technical delivery conditions for structural steels with improved atmospheric corrosion resistance. This steel grade is primarily used in construction and architectural applications, where its weather-resistant properties help ensure the structure's longevity and durability in challenging weather conditions.

The corrosion resistance of S355J2W is achieved through the formation of a protective patina on the surface of the steel. This patina acts as a barrier that prevents further corrosion from occurring, ultimately extending the lifespan of the material.
