TANTALUM FOR CHEMICAL PROCESSING INDUSTRY

The corrosion resistance, durability, workability, and heat transfer properties of tantalum make it ideal for challenging applications in the chemical industries. H.C. Starck’s engineered tantalum materials are used to produce condensers, coils, pipe spools, heat exchangers, and a variety of components exposed to corrosive fluids.

As experts in corrosion resistance, we are able to bring a focused, cost-effective approach to chemical processing challenges, with initiatives such as providing customers with ever thinner layer of tantalum, while maintaining superior corrosion resistance.

H.C. Starck’s tantalum provides superior performance in highly concentrated hot HCl and H2SO4 chemical environments. Its high strength and excellent corrosion resistance make tantalum ideal for use in the manufacture and repair of chemical process equipment and heat exchangers.
