Seamless Tube is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow tube. Billets are procured both from indigenous suppliers and from abroad. We carry a wide range of high-temperature seamless tubing, available in a variety of sizes and specifications, to be used in several industry for all kinds of high-temperature applications such as, thermocouple sheathes, burners, lance tubes, gas turbine, chemical processing, furnace equipment, jet engine combustion tubes, capillary tubes & heat exchangers.

We supply a full range of specialized Stainless Steel Seamless Tubes used for high-performance gas chromatography (GC) and liquid chromatography (LC) as components for chromatography columns used for analytical and preparative processes in diverse industries. To separate in very small sample sizes for very complex mixtures, these analyzes can be highly accurate and precise. Samples can be used for all kind of materials such as; water, gases, fuels, air, foods, flavorings, pesticides, plastics, drugs, tissue extracts. 321H SS Seamless tubes are available in various sizes ranging from 1/8" OD TO 2"OD, 3MM OD TO 38 MM OD.

Properties of SUS321H

Type 321 Cold Forming

Type 321 is easliy cold formed due to its ductile nature.

Type 321 Hot Forming

Type 321 can be readily formed and drawn.

Type 321 Machining

Type 321 is less machineable than Type 410 Stainless Steel.

Type 321 Welding

Type 321 is easily weldable by all standard techniques. No post weld treatment is required.

Type 321 Heat Treatment

Type 321 is non-hardenable by heat treatment. 321 is annealed by heating it to 1750 – 2050 °F (954 – 1121°C), then water quench or air cool.
