Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
904L is a high-performance stainless steel alloy known for its exceptional corrosion resistance and durability. It is often used in demanding industrial applications, especially in industries where resistance to harsh chemicals and extreme temperatures is critical. 904L flanges are a specific type of flange made from this alloy. Here is an introduction to 904L flanges.

Stainless Steel 904L Flanges Manufacturer

Stainless Steel 904L Flanges Exporter
ISO 9001:2015, PED/27/EC and OHSAS 18001:2015 Approved Manufacturer of Stainless Steel 904L Flanges in Specification ASTM A182 904L and Types Like 904L Weldneck Flange, 904L Blind Flange, 904L Socketweld Flange, 904L Slip On Flange, 904L Threaded Flange, 904L Laped Joint Flange, 904L Screw Flange, 904L Plate Flange, 904L WNRF Flange, BLRF Flange, SWRF Flange, 904L SORF Flange etc.
Material Composition: 904L is a non-stabilized low carbon, high alloy austenitic stainless steel. Its composition includes high levels of chromium, nickel, molybdenum, and copper. This unique combination of elements provides excellent resistance to corrosion and extreme environments.
Corrosion Resistance: The hallmark feature of 904L flanges is their outstanding corrosion resistance. They are highly resistant to a wide range of corrosive media, including sulfuric acid, acetic acid, phosphoric acid, and chloride-containing solutions. This makes 904L flanges suitable for applications in chemical processing, petrochemical, pharmaceutical, and offshore industries.
High Temperature Performance: 904L flanges can withstand elevated temperatures, making them suitable for applications where heat resistance is crucial. They maintain their mechanical properties at both high and sub-zero temperatures.
Durability: 904L stainless steel has a long service life due to its resistance to corrosion, which minimizes the need for frequent maintenance and replacements. This can result in cost savings over time.
Versatility: 904L flanges are available in various types, including slip-on, weld neck, blind, socket weld, and lap joint flanges, among others. This makes them suitable for a wide range of piping and equipment connections.
Weldability: 904L is weldable with conventional welding processes. However, it's essential to use appropriate filler materials to maintain its corrosion resistance after welding.
Standards and Specifications: 904L flanges are manufactured to meet various international standards and specifications, such as ASTM, ASME, and EN standards, depending on the specific application requirements.
904L flanges are a type of flange made from the highly corrosion-resistant 904L stainless steel alloy. They are widely used in industries where exceptional resistance to corrosion and extreme conditions is essential, making them a reliable choice for critical applications.
