Applications of ASTM A240 317L Steel
Chemical and Petrochemical Industry
Reactors and Piping: Used in manufacturing sulfuric acid condensers, pickling equipment, and chemical reactors to resist sulfuric acid, phosphoric acid, and acidic chlorides.
Storage Tanks and Heat Exchangers: Stable performance in media containing sulfides or chlorides, such as oil and gas field equipment.
Marine Engineering
Desalination Systems: Superior seawater corrosion resistance compared to 316L, suitable for heat exchangers, high-pressure reverse osmosis units, and submarine pipelines in desalination plants.
Marine Components: Used in ship piping, fasteners, and large-diameter butterfly valve parts (e.g., valve shafts and sleeves) to resist seawater erosion.
Energy Sector
Flue Gas Desulfurization (FGD) Equipment: In power plant FGD systems, absorption towers, spray systems, and flues require resistance to combined corrosion from chloride ions, sulfides, and low-temperature acids, making 317L steel an ideal choice.
Nuclear Power Plant Cooling Pipes: Its high-temperature and corrosion resistance suit nuclear energy applications.
Food and Pharmaceutical Industry
Sanitary-Grade Equipment: Used in manufacturing food processing equipment and pharmaceutical reactors, tolerating hot organic acids and fatty acids while meeting hygiene standards.
Other Fields
Textile Machinery: Corrosion resistance extends equipment lifespan.
Paper Industry: Used in corrosion-resistant components for pulp and paper machinery.
