Precision Tubes (Seamless Tube)

High performance precision tubes are cold drawn, drawn to a very high standard and they are known for their exceptional dimensional accuracy. Dimensional accuracy is of utmost importance in cold drawn tubes, especially in the automotive industry, where standards are exceptionally high. Good smoothness of internal and external surfaces is also absolute, particularly where tube connections make contact, as in automotive engines. And good consistency of mechanical properties is critical for performance and reliability.

What is a Stainless Steel Seamless Tube?

A seamless tube of stainless steel is a tubular product that is made without any welding seams, providing even strength and resistance throughout the structure. To manufacture these tubes, a solid billet is extruded through a die to give a flawless finish meaning there are no welds and no weak spots. Stainless steel seamless tubes are the right choice for applications involving high pressure, high temperatures, and corrosive environments. Whether strength, hygiene, or durability is the issue, these tubes can be relied upon to do the job.

Types of Precision Steel Tubes We Offer

At Amardeep Steel Centre, we provide a wide assortment of precision steel tubes custom made to fulfill several industrial requirements. Among our products, you will find cold drawn precision tubes, seamless precision tubes, stainless steel precision tubes, hydraulic precision tubing, and heat exchanger tubes. Each type is manufactured with strict adherence to tolerances, surface finish, and mechanical strength standards ensuring optimal performance in critical applications across sectors like automotive, aerospace, energy, and manufacturing.

Stainless Steel Precision Tubes Chemical Composition

Our stainless steel precision tubes are manufactured using high grade stainless steel, typically comprising:

• Chromium (Cr): 16-20% for corrosion resistance
• Nickel (Ni): 8-14% for toughness and oxidation resistance
• Molybdenum (Mo): 2-3% in specific grades for pitting resistance
• Carbon (C): ≤ 0.03% to ensure weldability and minimize carbide precipitation
• Manganese (Mn), Silicon (Si), Phosphorus (P), Sulfur (S): in trace amounts to balance properties

This precise composition ensures strength, durability, and resistance to harsh environments.

Precision Tubing Manufacturing Process

The precision tubing that we make starts with the extrusion of metal from a solid billet. This is the most basic way to form a tube shape. From there, we take the tubing and run it through a cold draw machine. Cold drawing is a basic way to refine a tube’s dimensions. Cold drawing also greatly improves the surface finish of the interior of a tube. So, after those two processes, we have heat-treated the tubing to ensure maximum strength and to relieve any stresses that might remain in the tubing after the previous two processes.

After heat treatment comes pickling. Now, that sounds sort of icky, but in truth, pickling is a very standard cleaning operation in any metal shop that’s worth its salt. Pickling removes unwanted surface contaminants. In a nutshell, after pickling, we passivate the tubing, which means we apply a very standard and totally safe process to make the oxide layer on the surface of the tubing more corrosion resistant.

Properties of Stainless Steel Seamless Tubes

Seamless tubes made from stainless steel have been discovered to possess the most extraordinary mechanical and chemical properties, which in turn render them ideal for the most demanding applications. They are known to have outstanding corrosion and oxidation resistance, which makes them perfect for high temperature, high pressure environments. They are also known to possess a very smooth internal surface, which ensures that fluids can flow through them efficiently. And in case you were curious, the food processing and pharmaceutical industries absolutely adore seamless stainless tubes. Those industries find the tube's nonreactive nature, their smoothness and their cleanliness to be perfectly in line with the requirements of those industries.
