904L stainless steel 

904L super austenitic stainless steel is a low-carbon high-nickel, molybdenum austenitic stainless acid-resistant steel, which is a proprietary material introduced by French HS company. It has good activation-passivation conversion ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, phosphoric acid, and good in neutral chloride-containing media. It is resistant to pitting and has good resistance to crevice corrosion and stress corrosion. Applicable to various concentrations of sulfuric acid below 70 C, resistant to corrosion at any concentration, any temperature of acetic acid and mixed acid of formic acid and acetic acid at normal pressure

application:
* Petroleum, petrochemical equipment, such as reactors in petrochemical equipment.
* Storage and transportation equipment for sulfuric acid, such as heat exchangers.
* Power plant flue gas desulfurization device, the main use parts are: tower body of the absorption tower, flue, door panel, internal parts, sprinkler system, etc.
* Washers and fans in organic acid treatment systems.
* Seawater treatment equipment, seawater heat exchangers, paper industry equipment, sulfuric acid, nitric acid equipment, acid production, pharmaceutical industry and other chemical equipment, pressure vessels, food equipment.
*Pharmaceutical plants: centrifuges, reactors, etc.
*Plant food: soy sauce cans, cooking wine, salt shakers, equipment and dressings.
* Strongly corrosive medium 0.45L for dilute sulfuric acid is a matching steel grade .
