Stainless Steel Tubing Supplier

Stainless Steel & Nickel Alloy Tube Supplier

We are a trusted nickel alloy and stainless steel tube supplier. Our tubes are used for structural strength with corrosion resistance. Our products are ideal for fabrication in chemical, acidic, fresh water, and salt water environments. Passing all of the required grades and standards, we promise that when you buy round & rectangular tube from Stainless Shapes, you buy from the best. Contact us for more information.

Types of Stainless Steel Tubes

Round Tube – Round tubes are hollow and cylindrical shapes that have multiple structural applications. Round tubes are often used in automotive parts, hollowed furniture, and industrial/commercial railings.

Rectangle/Square Tube – Rectangular tubes are ideal for modern and art deco construction. These reinforced and visually appealing shapes can reinforce buildings and constructions as well as show off its sleek design.

Tubing Finishes

Mill Finish – This is the surface texture it receives after it has been hot rolled off the line. This is the default feature for any hot rolled steel purchased.

180 – A grit belt or wheel finish will allow you to have what is known as an architectural finish. Finely polishing the grit lines in a uniform and directional appearance shows symmetry and a visually pleasing style.

240 – This is also called the dairy or sanitary finish. When you use a 240 grit belt, you can buff out the ridges in a way that bacteria cannot grow in the crevices. Often, bacteria will find its way into small areas to grow, but these are buffed out in 240. These are often seen as the surfaces for food service industries.

320 –  This creates a bright appearance with minimum haze. These are buffed before, known as a flawless buff.

400 Grit – This is the highest grit we can perform before we do grit touches to the metal. This will create a mirror finish, which is where you start being able to see minor reflections in the metal.

Polished – Polished to a very bright shine with zero haze, there are elements of upkeep to this style that should be administered.

Buffed – The brightest shine possible with some mirror reflections but unclear elements.

Mirror Buffed – This is buffed to such an extent that you can see a mirror reflection through the steel.

Stainless Steel Tubes

There are three main kinds of stainless steel used to make stainless steel tubes. Austenitic stainless steels have the highest corrosion resistance but the lowest structural strength. Ferritic steels are less corrosion-resistant than austenitic steels, but stronger. Martensitic steels are the strongest stainless steels available, but they have the weakest corrosion resistance. Hybrids of ferritic and austenitic steel are also increasingly common.

Stainless Steel Tubes

Tubes are available not only in cylindrical, square, and rectangular geometries, but also oval, triangular, hexagonal, and spiral options. 

Stainless steel tubes are generally made with grade 304 or 316 steel. Grade 304 steel resists heat and corrosion and is easy to weld. Grade 316 steel contains molybdenum as well as chromium, which imparts better corrosion resistance over 304 steel and holds up better at extremely high temperatures.

Stainless steel tubes and pipes are different and suit different use cases. When compared to pipes, tubes also have advantages and disadvantages:

  • Pros. Tubes have smoother, less sharply angled joints, and thus a less turbulent flow of fluid. Tubes resist leaks better than pipes do, and they can handle higher pressures. They’re also easier to install, maintain, and modify. 
  • Cons. Tubes are more expensive than pipes and take longer to manufacture.

Industries that rely on stainless steel tubes for their applications include:

  • Appliances
  • Automotive parts
  • Aircraft parts
  • Construction
  • Food handling
  • Furniture
  • Medical equipment
  • Structural parts
  • Water transport

Stainless Steel Pipes vs. Tubes

Pipes and tubes both carry fluid, and they’re similar enough that the terms are often used interchangeably. However, there are significant differences between pipes and tubes:

  • Pipe sizing focuses on the pipe’s capacity and interior diameter. Standard pipe sizes are measured using the nominal outside diameter sizing system.
  • Tube sizing is more concerned with structural strength, so tubes are measured based on their actual outside diameter and not the nominal outside diameter. This is especially important for applications that require narrow, precise widths, such as hypodermic tubing.

Stainless Steel Tubes From Stainless Shapes, Inc.

Stainless Shapes, Inc. manufactures a variety of tubes from stainless and steel and nickel alloy. Our tubes feature superior structural strength and corrosion resistance, making them ideal for use with chemicals, acids, or saltwater and freshwater. We offer both round and rectangular/square tubes:

  • Round. Round tubes are often used in vehicle parts, hollow furniture, and as railings in commercial and industrial facilities.
  • Rectangle/square. Popular for art deco construction, rectangular and square tubes offer aesthetic appeal while remaining strong enough to reinforce buildings.
