This Q235 + 304 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 304 stainless steel as the cladding layer to endow extreme rust resistance, corrosion resistance, acid-alkali resistance and aging 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. It supports full-specification customization, adapts to various high-demand working conditions, significantly reduces material costs while ensuring anti-corrosion performance, and provides a cost-effective and reliable composite metal solution for industrial manufacturing and engineering construction.
