Totten Tubes Inc
One of the most important considerations when evaluating steel tube is choosing the best material for your project. While many types of ASTM steel tube are available, two popular options include A513 and A500. While both deliver excellent performances in a variety of industries, they each have their own characteristics, applications, and advantages.

The Totten Tubes experts are here to help. This guide is designed to assist you as you compare A513 vs. A500 steel tube. Explore our stock list for more information about available steel tube options, and contact us with any questions.

A500 Structural Steel Tubing

ASTM A500 steel tubing is made from carbon steel and is a good choice for structural applications. It is available in square, rectangular, or round configurations. Several grades are offered:
  • Grade A (39,000 PSI Min. Yield)
  • Grade B (46,000 PSI Min. Yield)
  • Grace C (50,000 PSI Min. Yield)

Chemical Composition of A500 Steel Tube

The carbon steel used to manufacture A500 steel tubing is composed of mostly iron but also includes carbon, manganese, phosphorus, sulfur, and copper. The exact mix of these materials will vary depending on your selected grade.

How A500 Steel Benefits Your Assembly

A500 steel is an advantageous choice for building projects across industries. A few of the most notable benefits include:
  • High degree of weldability
  • High-strength capabilities
  • Excellent machinability
  • Ability to be cold worked
  • Aesthetically pleasing finish

The Best Applications for A500 Steel Tube

A500 steel tube is a versatile option for many building projects. Its high-strength capabilities and durability allow it to withstand exposed environments, extreme conditions, and other factors unique to your planned application. A500 steel tube is often used to build:
  • Bridges
  • Buildings
  • Skeletal support and framework for projects of all sizes
  • Welded, riveted, or bolted structures
  • Steam, water, and air transport systems

A513 Mechanical Steel Tube

ASTM A513 steel tube is one of the highest value steel materials currently on the market. It covers electric-resistant welded carbon and alloy steel, and it is ideal for use as mechanical tubing. A513 steel tube is offered in round, square, or rectangular configurations, with options such as:

Chemical Composition of A513 Steel Tube

Like A500, the majority of the chemical composition of A513 steel tube is iron, but it also contains carbon, manganese, phosphorus, silicon, and silver. The exact chemical makeup will vary depending on your selected type of A513 steel tubing.

The Advantages of A513 Steel Tubing

While A513 steel tube has a relatively low load-bearing capacity compared to A500, choosing it for your production comes with many benefits:
  • Ability to form tight tolerance, high-precision parts
  • Applicable to consumer product manufacturing
  • Cost-effective price point
  • Readily available
  • Highly durable

When to Choose A513 Steel Tube

While A513 steel tube shares many similarities with A500, it is significantly less durable and unsuited to heavy-duty structural assemblies. However, as it can be worked to much tighter tolerances, A513 performs considerably better for more precise projects:
  • Decorative handrails
  • Fencing
  • Ornamental fixtures
  • Industrial racking
  • Recreational vehicles
  • Lawnmower and landscaping equipment handles
  • Residential or commercial furniture

A513 vs. A500: Which Should You Pick?

When comparing A513 vs. A500 steel tube, choosing the best option for your application can be difficult and will depend on your project’s specifications. If you’re building large-scale structures such as buildings or bridges, choose A500. For commercial products that demand a higher rate of precision, choose A513.
