Alloy 31 plate sheet manufacturer supplier. Contact us to get free quote and sample!
Alloy 31 plate, with its carefully designed high alloy composition (high chromium, nickel, molybdenum, nitrogen and copper), has strong resistance to chloride pitting, crevice corrosion, stress corrosion cracking, and strong adaptability in complex acidic media such as sulfuric acid and phosphoric acid.
unsn08031 plate challenges in the chemical industry
Strong acid attack: Sulfuric acid, hydrochloric acid, phosphoric acid, mixed acid, etc. are widely used in reactions, catalysts, separation and purification processes.
Chloride threat: Chloride ions are commonly found in raw materials, catalysts, process water, and cooling media, which can easily cause pitting and stress corrosion cracking (SCC).
High temperature and high pressure: While improving reaction efficiency, it also accelerates the corrosion rate exponentially.
Complex media: Reaction intermediates, by-products, impurities, etc. may form unexpected corrosive combinations.
Wear and scouring: Slurry and high-speed fluids cause physical wear on the surface of equipment and destroy the passivation film.
application scenarios of Alloy 31 plates in the chemical industry
