SPA-H weathering steel plate

SPA-H weathering steel plate is a high-strength, corrosion-resistant steel plate with excellent atmospheric corrosion resistance, high temperature, abrasion, forming, fatigue, toughness and plasticity. SPA-H steel plate can form a dense protective layer between the stainless layer and the substrate, which can prevent oxygen and water in the atmosphere from penetrating into the steel substrate, slowing down the development of rust, thereby significantly improving the atmospheric corrosion resistance of steel.

Product Details

Implementation standard: JIS G 3125
Chemical composition: Carbon (C): ≤0.12, Silicon (Si): 0.25 - 0.75, Manganese (Mn): 0.20 - 0.50, Phosphorus (P): 0.07 - 0.15, Sulfur (S): ≤0.035, Copper (Cu): 0.25 - 0.60, Chromium (Cr): 0.30 - 1.25, Nickel (Ni): ≤0.65.
Performance: By adding alloy elements such as copper, chromium, and nickel, a stable and dense oxide film is formed on the surface of the steel plate, which effectively improves its corrosion resistance in the atmospheric environment, and its weather resistance is better than that of ordinary carbon steel.
Product features: Good atmospheric corrosion resistance and reduced maintenance costs. It has certain strength and toughness to meet the performance requirements of structural parts.
Application areas: Commonly used in building structures, such as the facades of large factories, stadiums, etc.
Applicable to outdoor steel structures such as bridges and towers. It is also used in the manufacture of railway vehicles and containers.
