Stainless steel 321 is a titanium-stabilized austenitic stainless steel that offers excellent resistance to intergranular corrosion when exposed to temperatures in the chromium carbide precipitation range of 800-1500°F (427-816°C). The addition of titanium also provides enhanced high-temperature properties. On the other hand, stainless steel 321H is a high carbon version of 321, specially developed for elevated temperature applications. The higher carbon content minimizes sensitization and improves high-temperature strength.

The pipe fittings made from these materials exhibit outstanding resistance to a wide range of corrosive environments, including organic acids, inorganic acids, and oxidizing and reducing environments. This corrosion resistance makes them suitable for use in harsh chemical processing environments where exposure to corrosive fluids is common.

One of the key advantages of stainless steel 321/321H pipe fittings is their superior weldability. These fittings can be readily welded using most standard welding techniques without the risk of intergranular corrosion. This characteristic simplifies fabrication processes and allows for the creation of complex structures and assemblies with ease.

Furthermore, stainless steel 321/321H pipe fittings offer excellent mechanical properties, including high tensile and yield strength, as well as good ductility and toughness, even at elevated temperatures. This combination of properties ensures that the fittings maintain their integrity and performance under demanding operating conditions.

In addition to their mechanical and corrosion-resistant properties, stainless steel 321/321H pipe fittings are also highly resistant to oxidation at high temperatures, making them suitable for use in applications where exposure to elevated temperatures is common, such as in heat exchangers and furnace components.

Stainless steel 321/321H pipe fittings are available in a variety of forms, including elbows, tees, reducers, couplings, and flanges, to suit different piping requirements and configurations. These fittings are typically manufactured according to industry standards such as ASTM A403/A403M for wrought austenitic stainless steel piping fittings.

It is essential to ensure proper material selection and fabrication techniques when using stainless steel 321/321H pipe fittings to maximize their performance and longevity. Proper handling, storage, and installation practices should also be followed to prevent contamination and damage to the fittings.

321H 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.
