Rolled composite steel plate/coil

Rolled composite steel plates use carbon structural steel, low-alloy high-strength structural steel or high-strength quenched and tempered steel as the base plate, and use composite rolling technology to organize one or both sides with stainless steel, special steel and other materials. After a certain degree of combination, the composite steel plate is obtained.

Rolled composite steel plate combines the material properties of different steel types. In terms of use function, it not only has the necessary strength of the base plate as a structural component material, but also meets the user's use performance and processing performance. At the same time, it also has the excellent properties of composite plate materials. Corrosion resistance, wear resistance, high strength and other functional properties. The rolled composite panel obtained by combining the base plate and the composite panel not only has excellent substitutability but also has better performance than the original product produced entirely with composite panel materials. Therefore, rolled composite steel plate is a more cost-effective and efficient composite material product.


Baosteel's rolled composite steel plates can be used in nuclear power, hydropower, pressure vessels, ship plates, structural steel, pipelines, decoration and other industries.
