Clad steel generates benefits in various cases, such as reducing overall piping costs and accommodating materials that can only be purchased in rare materials or thin sheets.
Clad steel is a composite material that uses carbon steel, high-strength steel, low-alloy steel, etc., as the base material, and combines it with a different type of steel on one side through processes such as hot rolling (bonding), welding, or explosive bonding. It allows for the joining of dissimilar metals, enabling the creation of functions that cannot be achieved with a single metal. By combining materials with good corrosion resistance or by using less expensive metals in larger quantities alongside more expensive ones, it is also possible to reduce the overall cost of piping. This type of steel provides advantages in various cases, such as accommodating rare materials or materials that can only be purchased in thin sheets. *The photo shows a cross-section of clad steel, where the combination of dissimilar metals can be seen.

basic information
The inner side is made of a cladding material for corrosion resistance, while the base material maintains strength. The thickness of the cladding material is generally around 3mm, and according to JIS (Japanese Industrial Standards) for steel, there are specifications for types such as stainless clad steel, nickel and nickel alloy clad steel, titanium clad steel, and copper and copper alloy clad steel. These are materials that are not easily procured and, being composite materials, require high technical skill for longitudinal welding. At Benkan Kiko, we are able to address these issues through our long-established sourcing of materials and welding technology.
