Clad steel plate is a composite material made from one or more types of steel. For instance, a stainless steel clad plate is produced using processes such as explosion welding, rolling, or explosive rolling to bind a stainless steel plate to an ordinary steel plate. This type of steel plate possesses characteristics of both types of steel: it has the corrosion resistance of stainless steel and the low cost and good stiffness of ordinary steel. Clad steel plate is designed to protect ordinary steel plates from corrosion. Methods such as electroplating, bonding, and spraying can be used to apply a protective "coat" on the surface of the steel plate, forming a clad steel plate.
There are many types of the clad steel plate, which can be classified into two main categories based on their combination type: metal clad steel plates and non-metal clad steel plates. Metal clad steel plates are those that are clad with other metal layers on the surface of the steel plate, such as stainless steel clad plates, titanium clad plates, copper clad plates, and aluminum clad plates. Non-metal clad steel plates are made from base steel plates combined with viscoelastic resins that have excellent vibration damping properties, such as lightweight clad steel plates and vibration-damping clad steel plates. Stainless steel clad plates and titanium clad plates are used to manufacture various storage tanks, pressure vessels, seawater desalination equipment, and as substitutes for precious metals like titanium and stainless steel in fields requiring corrosion resistance, such as chemical engineering, nuclear energy, and marine development.
Patterned steel is an early form of clad steel, consisting of a single steel body without alloy components. It is processed using semi-melting techniques, through stacking, hot forging or hot rolling, cold rolling, and shape processing to control internal material density and carbon content at bonding areas. This results in the fusion of different sizes of crystal grains within the steel! Due to differences in internal density and carbon content, chemical and mechanical properties vary at different layers, forming a structure with varying internal properties!
Aluminum clad steel plates are used to make electromagnetic cooking pots and conducting supports for linear motors, making full use of aluminum's excellent thermal and electrical conductivity and steel's ferromagnetic properties. Aluminum-steel clad plates are also used in household appliances, the automotive industry, and building sectors as corrosion-resistant materials. Dual-hardness armor plates used in military applications feature high-hardness steel on the outer layer and low-hardness steel on the inner side. These clad steel plates use the hard surface to shatter the steel core of armor-piercing projectiles, while the tough back material absorbs the impact without breaking, showcasing excellent comprehensive mechanical properties. Lightweight clad steel plates and vibration-damping steel plates, with their high specific stiffness and vibration resistance, are widely used in the automotive and aerospace industries.
