904L stainless steel is a highly corrosion-resistant alloy that provides excellent performance in a variety of applications, particularly in the water treatment and chemical processing industries. The following introduces the main performance characteristics of 904L stainless steel:

904L is an austenitic stainless steel containing high levels of chromium (19-23%), nickel (23-27%) and molybdenum (4-5%).
This unique chemistry provides excellent resistance to a variety of corrosive environments, including seawater, chlorides, acids and a wide range of chemicals.
904L offers excellent resistance to pitting, crevice and stress corrosion cracking, making it the first choice for applications where high corrosion resistance is critical.

The high nickel and molybdenum content in 904L stainless steel enhances its resistance to a wide range of chemicals, including strong oxidizing acids, reducing acids, and various organic compounds.
This chemical resistance makes 904L an ideal material for equipment, pipes and parts used in the chemical processing industry as well as in water treatment and desalination plants.

904L maintains its mechanical properties and corrosion resistance over a wide temperature range from cryogenic temperatures to high temperatures up to 600°C (1112°F).
This thermal stability is particularly beneficial for applications involving temperature fluctuations or exposure to high temperatures, such as in heat exchangers or high-temperature chemical processes.

904L stainless steel can be easily welded using a variety of techniques, including TIG, MIG, and plasma arc welding.
The material’s high ductility and formability make it easy to fabricate, including bending, rolling and machining, to produce a variety of parts and structures.
This manufacturing flexibility enables the design and construction of complex equipment and systems using 904L stainless steel.

904L stainless steel has good mechanical strength, with typical tensile strength of 550 to 750 MPa and yield strength of 220 to 450 MPa.
The material’s ductility and toughness make it suitable for applications where some degree of mechanical stress or impact is expected, such as piping systems or structural components.

The smooth, non-porous surface of 904L stainless steel, combined with its excellent corrosion resistance, makes it easy to clean and maintain a high level of hygiene.
This property is particularly important in food processing, pharmaceuticals and other industries where cleanliness and hygiene are critical.

Excellent corrosion resistance, chemical resistance, thermal stability and manufacturing flexibility combine to make 904L stainless steel a versatile, high-performance material with a wide range of applications, including water treatment, chemical processing and other industries field.
