This strong and durable material is resistant to corrosion, heat, and wear, making it suitable for use in some of the most demanding environments. One type of stainless steel that has gained much traction recently is the stainless steel hex tube. This blog post will explore everything you need about stainless steel hex tubes, including their properties, uses, and composition.

Stainless Steel Hex Tube: A Complete Guide to Properties, Uses and Composition


What is a Stainless Steel Hex Tube?

As the name suggests, a stainless steel hex tube is a hexagonal-shaped tube made from stainless steel. It uses an extrusion process, forcing a metal bar through a die to create a specific shape. The resulting tube has six sides, giving it a unique shape not found in other steel tubes.

Stainless Steel Hex Tube is a metal alloy tube comprising predominantly chromium, nickel and carbon. It is made from the same family of materials used to create stainless steel sheets and pipes but features hexagonal cross-sections. This design makes them strong, highly resistant to corrosion and rust, and easy to install in projects like handrails or frames. They are also inexpensive compared to other metals due to their natural abundance. Additionally, they can be joined with welds or threaded fittings for various applications, from industrial machinery parts down to simple nuts and bolts components for home improvement projects. With durable and cost-effective stainless steel hex tubes, this versatile solution makes them a favourite across many industries.

Properties of Stainless Steel Hex Tube

One of the main advantages of a stainless steel hex tube is its strength and durability. It is resistant to corrosion, which means it can be used in applications where it will be exposed to harsh environments such as saltwater or chemicals. It is also resistant to heat and wear, making it suitable for use in high-temperature environments and applications where the tube will come into contact with abrasive materials. Stainless steel hex tube is also easy to clean and maintain, which is important in applications where hygiene and sanitation are critical.

Uses of Stainless Steel Hex Tube

Stainless steel hex tube is used in various applications across different industries. Some common uses include:

Aerospace and Aviation:

Due to its strength and corrosion resistance, a stainless steel hex tube is used in aircraft parts such as landing gear and hydraulic systems.

Hydraulic and Pneumatic Systems: 

The unique shape of the hex tube allows for better pressure distribution, making it ideal for use in these systems.

Medical Devices: 

Due to its hygienic properties and ability to withstand sterilisation, a stainless steel hex tube is used to manufacture medical devices such as surgical instruments and implants.


Stainless steel hex tubes can be used in construction applications such as handrails and guardrails due to their strength and resistance to corrosion.

Composition of Stainless Steel Hex Tube

Stainless steel hex tubes are made from various alloys, the most common being 304 and 316 stainless steel. These alloys comprise chromium, nickel, and molybdenum, giving the tube different properties such as corrosion resistance and strength. The exact composition of the steel used to make the hex tube will depend on the specific application it will be used in, with some applications requiring a higher degree of corrosion resistance or strength.

Maintenance of Stainless Steel Hex Tube

While stainless steel hex tube is known for its durability, it still requires regular maintenance to ensure it remains in good condition. This includes cleaning the tube regularly to remove any dirt or debris that may have accumulated on the surface. Additionally, it’s important to avoid using harsh chemicals or abrasive materials when cleaning the tube, as this can damage the surface and reduce its corrosion resistance.


A stainless steel hex tube is a versatile and durable material that is suitable for use in a wide variety of different applications. Its unique hexagonal shape makes it ideal for use in hydraulic and pneumatic systems, while its strength and corrosion resistance make it popular in aerospace and medical device manufacturing industries. With regular maintenance and care, stainless steel hex tubes can last years and provide reliable performance in even the harshest environments.
