Product Description:
317L stainless steel is primarily used in more corrosive industrial environments where 316L stainless steel is unsuitable, especially in media containing high concentrations of chlorides and sulfuric acid.
Main application areas include:
Chemical and Petrochemical Industries (Core Area)
Reactors, tanks, pipelines, and heat exchangers for handling sulfuric acid, phosphoric acid, and chloride-containing mixtures.
Bleaching equipment in the pulp and paper industry (contact with high-temperature, high-chlorine bleaching solutions).
Equipment in the chemical fiber industry for handling sulfur- and chloride-containing chemicals.
Environmental Protection and Flue Gas Treatment
Key components in wet flue gas desulfurization systems, such as absorber inlet flues, slurry spray zones, and demisters, to resist the synergistic corrosion and abrasion of high concentrations of chloride ions, sulfuric acid, and solid particles.
Marine and Seawater Applications
Key components such as heat exchanger tube sheets and water chambers in seawater cooling systems.
Marine components with higher requirements than 316L.
Energy Industry
Flue gas scrubbing towers and waste heat recovery systems in coal-fired power plants.
Components in geothermal power generation equipment that come into contact with high-salinity geothermal fluids.
Food and pharmaceutical industries
High-standard equipment that comes into contact with high concentrations of chlorine-containing cleaning agents or salts.
Equipment for concentrating and storing acidic foods such as vinegar and soy sauce.
