Stainless Steel 321H Tubing Stockist

Stainless Steel 321 and 321H are popular for high-temperature applications due to their excellent resistance to intergranular corrosion. Adding titanium to the material stabilizes it, making it less sensitive to intergranular corrosion and more durable in harsh working environments.

Composition and Material of 321 Tubings
The composition of Stainless Steel 321 tubing includes carbon, manganese, phosphorus, sulfur, silicon, nickel, and chromium, along with other elements like nitrogen, molybdenum, titanium, and copper. These elements significantly enhance the overall properties of Stainless Steel 321 Tubings and piping. They contain 18% chromium and 8% nickel, typical for standard austenitic 18/8 chromium-nickel alloys. The presence of titanium in the composition makes them ideal for high-temperature applications, withstanding environments up to 900 degrees Celsius.

Features of Stainless Steel 321H Tubings
Stainless Steel 321H tubes offer exceptional resistance like Stainless Steel 347H Tubings to temperatures of 427 to 816 degrees Celsius, making them ideal for applications in the chromium carbide precipitation range. These tubings are the modified version of Stainless Steel 321 with a high carbon content, which enhances their high-temperature strength.

Uses of Stainless Steel 321 Tubings
Stainless Steel 321 Tubings are highly suitable for use in operating temperature environments of over 500 degrees Celsius. Some common uses for Stainless Steel 321 tubings include aircraft exhaust systems, heat exchangers, and chemical processing equipment. The durability and corrosion resistance of Stainless Steel 321 makes it a popular choice for a variety of applications across many different industries.

Manufacturing Process of Stainless Steel 321/321H Tubing
Stainless Steel 321/321H Tubing uses a seamless or welded manufacturing process, depending on the application requirements. The tubing is produced in various sizes, from small-diameter tubes to large-diameter pipes, with thicknesses ranging from thin to heavy walls.

Seamless tubing is produced by piercing a solid stainless steel billet with a mandrel and then drawing the tubing through a die to create the desired diameter and wall thickness. Welded tubing, conversely, is made by rolling a flat strip of stainless steel into a tube shape and welding the seam using various welding techniques such as TIG, MIG, or plasma welding.

After manufacturing, the tubing is subjected to various finishing processes, such as annealing or pickling, to remove surface imperfections and enhance its mechanical and corrosion resistance properties. The finished tubing is then cut to the desired length and inspected to ensure it meets the required specifications before it is ready for use. The tubing undergoes finishing processes and quality inspections to meet the required specifications.

At Kalp Industries, we supply a wide range of Stainless Steel 321/321H Tubings made from premium quality raw materials, which are generally used in various industries to transport produced fluids or liquids for formation to the surface. We offer customized forms of these tubings to meet the unique dimensions and shapes required by our clients. The company also supplies quality Stainless Steel 317 Tubing that offers versatility in various applications.
