SS 904L Flanges Supplier

Stainless steel is a metal alloy composed of iron and other elements, most commonly chromium. It is highly corrosion-resistant and can be used for various applications. One type of stainless steel, 904H, has become increasingly popular due to its strength and durability.
Stainless Steel 904L Flanges can be used in many different industries for various purposes. They are often used in the oil and gas industry for connecting pipes and in chemical processing plants for connecting valves or pumps to pipes. They can also be used in food processing facilities due to their resistance to corrosion from acidic materials such as vinegar or lemon juice. Additionally, they are commonly found on ships and boats due to their durability against harsh weather conditions at sea. At Metcore Steel, we pride ourselves on providing excellent customer service and offering a wide range of products, including Stainless Steel 904L Flanges and Super Duplex Steel UNS S32760 Flanges.

The main benefit of using SS 904L Flanges is that they are significantly resistant to corrosion, making them ideal for long-term use in harsh environments such as offshore or in chemical processing plants. Additionally, they can withstand temperatures up to 600°F, which makes them perfect for applications that require high heat resistance, such as power plants or boilers. In addition to our range of Stainless Steel 904L Flanges we also offer a variety of Stainless Steel 310 Flanges to meet your piping needs.

They offer an excellent seal between two connected surfaces. That helps prevent leaks or contamination from outside sources, such as dirt or water infiltration into pipes or valves where seals may have been compromised over time due to wear and tear from usage.

Stainless Steel 904L flanges offer many benefits compared to other metal alloys, such as aluminum or brass. They provide superior strength and durability and increased resistance against corrosion, making them perfect for applications where long-term use is required under extreme environmental conditions like those found offshore or on ships at sea.

Stainless steel 904L flanges come in several types: threaded, slip-on, weld neck, socket weld, lap joint, blind and plate flanges. For example, threaded flanges are used in low-pressure piping systems, while weld neck flanges are best suited for high-pressure systems.


904L stainless steel flanges are commonly used in applications that require corrosion resistance, such as chemical processing, pharmaceuticals & offshore oil & gas production. They offer excellent resistance to corrosion in a wide range of environments, including those that are highly acidic or contain chloride.
The main difference between 304L and 904L flanges is the composition of the stainless steel. 904L stainless steel contains more nickel, chromium, and molybdenum than 304L stainless steel, making it more corrosion-resistant & better suited for harsh environments.
SS 904L flanges are pipe fitting made from grade 904L stainless steel. These flanges are designed to provide a strong & reliable connection between two pipe sections or between a pipe & a valve, pump, or other equipment. They are commonly used in applications where corrosion resistance is required.
