Stainless Steel 904L Flanges are flanges made from the stainless steel grade 904L. This grade is a low carbon, high-nickel and molybdenum austenitic stainless steel with added copper. The chemical composition of Stainless Steel 904L typically includes approximately 19-23% chromium, 23-28% nickel, 4-5% molybdenum, and 1-2% copper. These alloying elements contribute to its exceptional corrosion resistance properties and overall performance.

One of the key features of Stainless Steel 904L Flanges is their outstanding corrosion resistance in various aggressive environments. The high chromium and nickel content, combined with molybdenum and copper, enable these flanges to resist pitting and crevice corrosion in chloride-containing media, such as seawater and acidic solutions. This makes 904L flanges ideal for applications in marine environments and chemical processing industries where resistance to corrosion is critical.

Stainless Steel 904L Flanges are known for their excellent toughness, weldability, and formability. They offer good strength and can withstand cryogenic temperatures, making them suitable for low-temperature applications as well. The low carbon content in this grade minimizes the risk of carbide precipitation during welding, which enhances its weldability and reduces the likelihood of intergranular corrosion.

Regarding heat treatment, Stainless Steel 904L Flanges are typically solution annealed at temperatures ranging from 1090°C to 1175°C (1995°F to 2145°F), followed by rapid cooling. This treatment ensures the material's homogeneity and restores its corrosion resistance properties, especially after welding.

 Stainless Steel 904L Flanges

Stainless Steel 904L Flanges find a wide range of applications in industries such as chemical processing, petrochemical, oil and gas, pharmaceuticals, and desalination plants. They are commonly used in equipment like heat exchangers, pressure vessels, and storage tanks, where resistance to corrosive environments is paramount. Additionally, these flanges are employed in components for handling sulfuric acid and other aggressive chemicals, making them indispensable in industries with demanding corrosion-resistant requirements.
