800HT Incoloy alloy flange

Incoloy is suitable for all concentrations of sulphuric acid at low temperatures; In 50% ~ 70% concentration of caustic alkali solution (such as NaOH), it has good corrosion resistance and does not produce stress corrosion cracking. Inconel is suitable for various solutions and acids containing Cl -, and many media such as caustic alkali with concentration < 70%.
