Hastelloy B is an alloy developed for resistance to hydrochloric acid, capable of withstanding hydrochloric acid at all concentrations and throughout the entire temperature range up to its boiling point. It is also suitable as a corrosion-resistant material for sulfuric acid, phosphoric acid, hydrofluoric acid, and acetic acid. However, the presence of oxidative factors such as iron ions and copper ions can accelerate corrosion. Examples of applications include towers, tanks, and heat exchangers in the petrochemical industry (such as PVC, polyethylene, polystyrene, benzene, etc.), as well as sulfuric acid production equipment. Yura Sansho Co., Ltd., a supplier of industrial fasteners, will propose solutions as a technical trading company for all fastening-related issues, including high strength, heat resistance, corrosion resistance, and loosening. We supply optimal products tailored to customer needs, from short delivery times and small lots to long-term and large-scale demands.
