This Q235 + 2205 metal composite steel plate achieves atomic-level metallurgical bonding of two metals through advanced metallurgical cladding technology. It uses Q235 carbon steel as the base layer to provide excellent structural strength, welding processability and cost-effectiveness, and 2205 duplex stainless steel as the cladding layer to endow extreme acid-alkali resistance, chloride ion corrosion resistance and stress corrosion cracking resistance, perfectly combining the high strength of duplex steel with the economy of carbon steel. The product has high bonding strength at the composite interface, no delamination and no bubbles, and can withstand full-process deep processing such as cutting, bending, U-bending, stamping and welding, with excellent processability. Especially suitable for harsh corrosion working conditions such as marine, chemical and oil and gas, it significantly reduces the cost of pure 2205 duplex steel while ensuring extreme anti-corrosion performance, providing a cost-effective and reliable composite metal solution for high-end anti-corrosion engineering, marine equipment and chemical equipment.
