Stainless Steel 310 and 310S are popular grades of austenitic stainless steel known for their high-temperature resistance and excellent corrosion resistance properties. Pipe fittings made from these materials are widely used in various industries including petrochemical, chemical, food processing, and power generation. In this brief overview, we'll discuss the key features, applications, and advantages of Stainless Steel 310/310S pipe fittings.

Key Features of Stainless Steel 310 / 310S Pipe Fittings:

High Temperature Resistance: One of the primary advantages of Stainless Steel 310/310S pipe fittings is their exceptional resistance to high temperatures. These alloys can withstand temperatures up to 1150°C in continuous service and 1035°C in intermittent service, making them suitable for applications involving elevated temperatures such as furnace parts, heat treatment equipment, and thermal processing units.

Corrosion Resistance: Stainless Steel 310 Buttweld Pipe Fittings exhibits excellent corrosion resistance in various environments, including oxidizing and reducing atmospheres. They resist corrosion by forming a passive oxide layer on the surface, which protects the underlying material from degradation. This corrosion resistance makes them suitable for use in corrosive environments encountered in chemical processing, marine, and offshore applications.

Strength and Durability: Stainless Steel 310S Buttweld Pipe Fittings offer good mechanical properties, including high tensile strength and toughness, which contribute to their durability and reliability in demanding industrial applications. They maintain their strength and integrity even at high temperatures, ensuring long-term performance under challenging operating conditions.

Versatility: Stainless Steel 310 pipe fittings are versatile and can be easily fabricated into various shapes and sizes to meet specific requirements. They are available in different forms such as elbows, tees, reducers, couplings, and flanges, providing flexibility in design and installation.

Applications of Stainless Steel 310 / 310S Pipe Fittings:

Chemical Processing: Stainless Steel 310S pipe fittings are widely used in chemical processing industries for handling corrosive chemicals and acids. They are preferred for their corrosion resistance and reliability in harsh chemical environments.

Petrochemical Industry: These alloys find extensive use in the petrochemical industry for piping systems transporting high-temperature fluids and gases. They are suitable for refinery operations, petrochemical plants, and oil and gas processing facilities.

Power Generation: Stainless Steel 310/310S pipe fittings are utilized in power generation plants for applications such as boiler tubing, heat exchangers, and exhaust systems. Their high-temperature resistance makes them ideal for use in boilers and thermal power equipment.

Food and Beverage: In the food and beverage industry, Stainless Steel 310S pipe fittings are preferred for sanitary applications due to their hygienic properties and corrosion resistance. They are used in processing equipment, piping systems, and storage tanks for handling food products and beverages.

310S Stainless Steel Pipe Fittings Manufacturing Process

Hot forming or Extrusion Method

By forcing a heated billet through a molded die's opening, forged parts are produced by the process of hot extrusion. This article discusses lubricated versus non-lubricated hot extrusion.

Hydraulic Bulge method – Cold forming

Internal pressure and axial feeding are used in hydroforming tube to create the perfect sort of tube. The operation's results can be predicted using the finite-element method.

Deep Drawing Method for caps

Some of the most widely used techniques for creating caps involve cutting the plate into a circle and shaping it with a deep draw. The process of deep drawing sheet metal storage, also known as blanks, creates a circular or irregular shape that is longer than half of its diameter.

Flare Method for Stub ends

The flaring procedure is used to create lap joint flanges and stub ends. A flare or flange face with a cutout called the flow end. Welding is frequently used to generate stub ends after the forge block has been machined to the desired size.
