If you are looking for a combination of light weight, lower cost, good strength, corrosion resistance and thermal and electrical conductivity in a single metal, just consider the clad plates.
Clad steel plate is a combination of two or more different metals, each chosen for its specific properties, metallurgically bond to obtain an integral continuous single metal material superior to that of any of the individual metals taken alone. The base material in the composite is carbon steel or alloy steel and is the thicker of the two metals. This economical base material provides the required strength and structural integrity to the composite. The thinner layer of the composite, usually ranging between 10% and 20% of the total thickness, but still available from 5% to 40%, may be stainless steel, aluminum and aluminum alloy, copper and copper alloy, nickel and nickel alloy, titanium etc. The cladding material is normally selected for corrosion resistance and allows the designer to gain the desired benefit of solid high-alloy plate.
The clad sheet from KLS can be cut, welded or formed into a finished part ranging from reactors, chemical processing chambers, heat exchangers, tanks and pressure vessels to small applications and clad pipe. Due to the superior properties offered by clad metals and the wide variety of available cladding material and base materials, the clad steel plate can be combined to make customized materials for a wide variety of demanding industries like chemical & petroleum processing, paper making and pulp, food processing, power generation, water supply and municipal construction etc.
