**Hastelloy Flat Bars** are applied extensively in **chemical processing equipment, heat exchangers, pressure vessels, flue gas scrubbers, reactors, evaporators, and marine components**. Their exceptional corrosion resistance renders them suitable for the handling of **sulfuric acid, hydrochloric acid, chlorine gas**, and **wastewater treatment**. These flat bars are also used in **pulp & paper**, **power generation**, and **nuclear fuel reprocessing** plants. Due to their great weldability and formability, Hastelloy flat bars are the choice for custom-made parts and structures that work in highly corrosive and high-stress environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
