Stainless Steel 310 and 310S forged fittings are high-alloy austenitic steels primarily made of iron, featuring 24–26% chromium and 19–22% nickel, with 310S having a lower carbon content for better weldability. These materials boast remarkable oxidation resistance at elevated temperatures, reaching up to 1100°C, while maintaining strength and toughness under thermal stress. The alloys are also resistant to corrosion in oxidizing environments, exhibit high tensile strength, good creep resistance, and retain dimensional stability during extended heat exposure, making them perfect for high-temperature industrial applications where durability and performance are essential.

These fittings are highly resistant to oxidation and corrosion at elevated temperatures. They are designed for high-pressure applications and come in various sizes typically ranging from 1/2 inch to 4 inches. Socket weld fittings are ideal for applications requiring a strong, leak-proof connection.
Threaded fittings in SS 310 offer excellent resistance to oxidation and corrosion, especially in high-temperature environments. Sizes generally vary from 1/8 inch to 4 inches. They are used for connecting pipes with threads, making them suitable for pressure-tight joints.
These elbows provide excellent corrosion resistance and are ideal for applications involving high temperatures. They are available in sizes from 1/2 inch to 4 inches and are used to change the direction of flow in piping systems by 45 degrees.
Threaded tees made of SS 310 exhibit superior resistance to high-temperature oxidation and corrosion. Common sizes range from 1/4 inch to 4 inches. These tees are used to branch out pipelines and provide a secure connection in high-pressure systems.
Offering excellent corrosion resistance, threaded half couplings are used to connect two pipes in high-temperature applications. Sizes typically range from 1/8 inch to 4 inches. They are ideal for creating a connection in the middle of a pipe.
Socket weld crosses in SS 310S provide high resistance to oxidation and are used in high-pressure systems. They are available in sizes from 1/2 inch to 4 inches and allow for the intersection of four pipes, ensuring a robust connection.
Stainless Steel 310 and 310S forged fittings find extensive use in industries that demand high-temperature resistance and corrosion protection. They are particularly suited for furnace components, heat exchangers, kilns, boilers, and petrochemical pipelines, where extreme conditions are the norm. Their ability to endure thermal cycling, oxidation, and chemical exposure makes them ideal for power plants, chemical processing facilities, and refineries. Moreover, 310/310S forged fittings are also utilized in food processing and pharmaceutical equipment due to their sanitary characteristics.
