Try explosion clad steel for corrosion protection

Corrosion-resistant alloys are frequently required in chemical process industries (CPI) environments. The initial cost of such equipment is typically much higher than that of carbon steel and nonmetals. This is particularly true when elevated temperatures and high pressures necessitate heavy wall thicknesses. The initial cost of equipment can often be reduced significantly by the use of clad construction. Explosion cladding of a relatively thin layer of corrosion-resistant alloy onto a thicker, lower cost steel has proven to be a reliable and cost-effective alternative. For many combinations of metals type, thicknesses, and technical requirements, explosion clad is the lowest cost, highest value solution. Commonly used clad alloys include stainless steels, nickel alloys, copper alloys, titanium, and zirconium, all bonded to carbon and alloy steels. Explosion cladding is a solid state metal-joining process that uses explosive energy to create an electron-sharing metallurgical bond between two metal components. Although the explosive detonation generates considerable heat, there is no time for heat transfer to the component metals; consequently, there is no appreciable temperature increase in the metals.
