IRSM 41-97 Corten steel sheet and plate is a robust, corrosion-resistant weathering steel that was originally developed for the Indian Railways but has since found its way into various sectors, including infrastructure, architecture, and industry. This steel is celebrated for its self-weathering properties, which allow it to develop a protective rust-like layer when exposed to the elements. This unique feature means it doesn’t require painting, leading to lower maintenance costs. With impressive mechanical strength, durability, and resistance to atmospheric corrosion, especially in tough and polluted environments, it’s a reliable choice. The steel comes in various thicknesses and dimensions, making it suitable for both structural and decorative uses.
IRSM 41-97 Corten Steel Sheet and Plate is a weathering steel with a unique composition, providing excellent corrosion resistance. Its typical chemical composition includes Carbon (0.12-0.2%), Manganese (0.6-1.5%), Phosphorus (0.05%), Sulfur (0.03%), and Copper (0.25-0.55%), along with Chromium, Nickel, and Silicon for enhanced strength and durability. Mechanical properties include a Yield Strength of 250 MPa, Tensile Strength ranging from 440 to 600 MPa, and an elongation of 20% in 200mm. This steel is ideal for outdoor structures, offering long-term protection against corrosion.
