904L austenitic stainless steel belongs to low-carbon, high nickel, molybdenum austenitic stainless steel with acid resistance. 904L austenitic stainless steel has excellent activation passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, good resistance to pitting corrosion in neutral chloride ion media, and good resistance to crevice corrosion and stress corrosion. Suitable for various concentrations of sulfuric acid below 70 ℃, it has good corrosion resistance to any concentration and temperature of acetic acid and a mixture of formic acid and acetic acid under normal pressure.

Austenitic stainless steel 904L is a high alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for environments with harsh corrosion conditions. It has a high chromium content and sufficient nickel content. The addition of copper gives it strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is less prone to corrosion spots and cracks, and its resistance to pitting corrosion is slightly better than other steel grades. It has good machinability and weldability and can be used in pressure vessels.

904L is a low carbon content, high alloying austenitic stainless steel designed for harsh corrosive environments. It has better corrosion resistance than 316L and 317L, while balancing price and performance, and has a higher cost-effectiveness. Due to the addition of 1.5% copper, it has excellent corrosion resistance for reducing acids such as sulfuric acid and phosphoric acid. It also has excellent corrosion resistance to stress corrosion, pitting corrosion, and crevice corrosion caused by chloride ions, and has good resistance to intergranular corrosion. In pure sulfuric acid with a concentration range of 0-98%, the usage temperature of 904L can reach up to 40 degrees Celsius. In pure phosphoric acid with a concentration range of 0-85%, its corrosion resistance is very good. Impurities have a strong impact on the corrosion resistance of industrial phosphoric acid produced by wet process technology. Among all types of phosphoric acid, 904L has better corrosion resistance than ordinary stainless steel. In highly oxidizing nitric acid, 904L has lower corrosion resistance compared to high alloyed steel grades without molybdenum. In hydrochloric acid, the use of 904L is limited to lower concentrations of 1-2%. Within this concentration range. The corrosion resistance of 904L is better than that of conventional stainless steel. 904L steel has high resistance to pitting corrosion. Its resistance to crevice corrosion in chloride solution. The force is also very good. The high nickel content of 904L reduces the corrosion rate in pits and crevices. Ordinary austenitic stainless steel may be sensitive to stress corrosion in an environment rich in chloride at temperatures above 60 degrees Celsius. By increasing the nickel content of the stainless steel, this sensitization can be reduced. Due to its high nickel content, 904L exhibits high resistance to stress corrosion cracking in chloride solutions, concentrated hydroxide solutions, and environments rich in hydrogen sulfide.

Petroleum and petrochemical equipment, such as reactors in petrochemical equipment, storage and transportation equipment for sulfuric acid, such as heat exchangers, power plant flue gas desulfurization devices, mainly used in the tower body, flue, door panels, internal components, spray systems, etc. of absorption towers, scrubbers and fans in organic acid treatment systems, seawater treatment devices, seawater heat exchangers, papermaking industry equipment, sulfuric acid and nitric acid equipment, acid production, etc Pharmaceutical industry and other chemical equipment, pressure vessels, food equipment, pharmaceutical factories: centrifuges, reactors, etc., plant food: soy sauce tanks, cooking wine, salt tanks, equipment and dressings, 904L is a matching steel grade for dilute sulfuric acid strong corrosive medium.

Plate, strip, bar, wire, forging, smooth rod, welding material, flange, etc., can be processed according to the drawing
