UNS N08904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. The stainless steel 904L pipe is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. With the addition of molybdenum, 904L pipes offer enhanced resistance to crevice corrosion, making them perfect for general corrosion applications and moderate to high-temperature conditions. Mechanical tests such as tension and flattening are performed on Stainless steel 904L pipes to ensure strength and durability. These pipes are heat-treated according to ASTM A312 standards for optimal performance.
Jinie Technology (Jiangsu) Co., LTD supplies premium 904L stainless steel pipes, known for their high alloy composition and low carbon content. This non-magnetic, austenitic stainless steel 904L pipe contains copper, making it highly resistant to strong acids like sulfuric acid. The low carbon content allows for easier production under ASTM A312 specifications, making it ideal for high-temperature applications. The high chromium content promotes and maintains a passive film which protects the material in many corrosive environments. 904L pipe has a greater resistance to precipitation of ferrite and sigma phases on cooling and welding than other stainless steels containing molybdenum. There is no risk of intercrystalline corrosion on cooling or welding due to the low carbon content. Its maximum service temperature is at 450°C.
