A comprehensive overview is provided of the principles involved in designing and fabricating equipment made from clad steel, a material that combines the structural strength of carbon steel with the corrosion resistance of stainless steels or nickel-based alloys. The content reviews manufacturing routes for clad products, key metallurgical and mechanical properties, and essential considerations for welding, forming, inspection, and quality control. Typical applications in the chemical, petrochemical, refining, and power industries are also outlined, with emphasis on how clad steel enhances durability while reducing overall lifecycle costs.
