Stainless Steel 904L Flange Definition

904L Stainless Steel Flanges are made up of a nickel chromium austenitic stainless steel which has 23% nickel and 19% chromium minimum in the composition with carbon, manganese, silicon, phosphorus, sulfur, copper and 4% molybdenum to it.

Stainless Steel 904L is a high-alloy austenitic stainless steel that is known for its excellent corrosion resistance, especially in harsh environments. It contains high amounts of chromium, nickel, and molybdenum, UNS S32750 which contribute to its exceptional performance in corrosive conditions. Stainless Steel 904L Flanges, often abbreviated as SS 904L Flanges, are critical components in piping systems, providing a reliable and durable connection between pipes, valves, and other equipment.

Key Features of Stainless Steel 904L:

Corrosion Resistance:

SS 904L exhibits superior corrosion resistance, making it suitable for applications in aggressive environments such as chemical processing, petrochemical, and marine industries.

High Strength:

The alloy has high tensile and yield strength, ensuring the durability and longevity of components made from SS 904L.

Heat Resistance:

Stainless Steel 904L maintains its mechanical properties at elevated temperatures, making it suitable for applications involving high temperatures and thermal cycling.


SS 904L is readily weldable, allowing for the fabrication of complex structures and connections without compromising its corrosion resistance.

Introduction to Stainless Steel 904L Flanges:

Stainless Steel 904L Flanges are integral parts of piping systems, serving as connectors that facilitate the assembly and disassembly of pipes, valves, and other equipment. These flanges are designed to provide a leak-tight seal and ensure the integrity of the piping system. Common types of flanges include slip-on flanges, weld neck flanges, blind flanges, Socket Weld Flange and Lap Joint Flange, among others.

Key Attributes of SS 904L Flanges:

Corrosion Resistance:

  • Just like the base material, SS 904L Flanges offer excellent corrosion resistance, making them suitable for corrosive environments.


  • These flanges are often used in applications involving acids, such as sulfuric acid and phosphoric acid, where conventional stainless steels may fail.


  • Stainless Steel 904L Flanges are versatile and find applications in various industries, including chemical processing, pharmaceuticals, oil and gas, and seawater desalination.

Dimensional Precision:

  • The flanges are manufactured with high precision to ensure proper alignment and fit within the piping system, minimizing the risk of leaks.

Stainless Steel 904L Flanges or Weld Neck Flangeplay a crucial role in ensuring the reliability and longevity of piping systems in demanding and corrosive environments. Their combination of corrosion resistance, high strength, and weldability makes them a preferred choice for industries where durability and performance are paramount.

Stainless Steel 904L Flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Stainless Steel 904L Flange is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L is non-magnetic, and offers excellent formability, toughness and weldability.

Stainless Steel 904L Flange contains high amounts of expensive ingredients, such as molybdenum and nickel. Today, most of the applications that employ grade 904L are replaced by low-cost duplex stainless steel 2205.
