This Q235 + 316L 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 316L ultra-low carbon stainless steel as the cladding layer to endow extreme acid-alkali resistance, chloride ion corrosion resistance and intergranular corrosion resistance, perfectly combining the core advantages of both metals. 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, stamping and welding, with excellent processability. Especially suitable for strong corrosion working conditions such as marine, chemical and pharmaceutical, it significantly reduces the cost of pure 316L stainless steel materials 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.
