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. 304HSS Seamless tubes are available in various sizes ranging from 1/8" OD TO 2"OD, 3MM OD TO 38 MM OD. The thickness of SS 304H tube ranges from 1MM TO 3 MM, 0.028 TO 0.156 IN. AISI 304H Seamless tubes are available in Indian, European and Japanese origin.

Properties of SUS304H
304H SS Cold Forming
304H Stainless Steel is readily formed and fabricated through a full range of cold working operations. It can be used in heading, drawing, bending, and upsetting. Any cold working operations will increase the strength and hardness of the material, and may leave it slightly magnetic.
304H SS Hot Forming
304H Stainless Steel can be forged in the 1700-2200°F range. For maximum corrosion resistance, forgings should be annealed at 1900°F minimum and water quenched or rapidly cooled by other means after hot working operations.
304H SS Machining
304H Stainless Steel is a tough austenitic stainless steel subject to work hardening during deformation and, unless modified for improved machining response, is resistant to chip breaking. The best machining results are achieved with slower speeds, heavier feeds, excellent lubrication, sharp tooling, and powerful, rigid equipment.
304H SS Welding
304H Stainless Steel is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E308H/ER308H filler metals should be used with Type 304/304H steel. After welding Type 304H it may be necessary to fully anneal to restore the corrosion resistance lost by sensitization to intergranular corrosion when chromium carbides were precipitated in the grain boundaries in the weld heat-affected zone.
304H SS Heat Treatment
Annealing: Type 304H should be heated to 1900ºF minimum and water quenched or rapidly cooled by other means.
Hardening: Type 304H cannot be hardened by heat treatment. However, Type 304H can be hardened by cold working.
