Valour Alloys Inc., we carry a full inventory and Supply Stainless Steel 304 / 304L Flanges products in a variety of sizes widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
SS 304 / 304L Flanges are manufactured using chromium and austenitic nickel alloy. These Flanges provide outstanding corrosion resistance. SS 304/304L Flanges are very popular to use at high temperatures. These flanges can be formed into a variety of shapes, dimensions and sizes.
304 and 304L are popular grades of stainless steel, and flanges made from these materials are commonly used in various industries. Here's an introduction to 304 and 304L flanges
304 Stainless Steel: 304 is an austenitic stainless steel grade that contains 18-20% chromium and 8-10.5% nickel. It is known for its excellent corrosion resistance, high-temperature strength, and good formability. This grade is widely used in various applications, including food processing, chemical processing, and architectural structures.
304L Stainless Steel: 304L is a low-carbon variant of 304 stainless steel, with a maximum carbon content of 0.03%. The lower carbon content helps to reduce the risk of sensitization and subsequent corrosion in certain environments. 304L is often preferred for welding applications where post-weld sensitization is a concern.

Types: Flanges are components used to connect pipes, valves, and other equipment in a piping system. 304 and 304L stainless steel flanges are available in various types, including weld neck flanges, slip-on flanges, blind flanges, socket weld flanges, and threaded flanges. Each type has specific advantages and is chosen based on the application requirements.
Corrosion Resistance: 304 and 304L flanges offer excellent resistance to corrosion in a wide range of environments, including acidic, alkaline, and chloride-containing solutions. This makes them suitable for applications in chemical processing, water treatment, and food and beverage industries.
High-Temperature Strength: These flanges maintain their mechanical properties at elevated temperatures, making them suitable for applications where the system operates at high temperatures.
Weldability: Both 304 and 304L stainless steel flanges are readily weldable and can be used in welded piping systems. The low carbon content in 304L reduces the risk of sensitization and subsequent corrosion in the heat-affected zone during welding.
304 and 304L flanges are popular choices in various industries due to their excellent corrosion resistance, high-temperature strength, and weldability. Their versatility makes them well-suited for a wide range of applications where a reliable and durable connection between components in a piping system is required.
