ASTM A513 Specification and Performance

Contents
erw carbon steel pipe

ASTM A513 steel pipe is a high-carbon alloy with a strong, seamless, and consistent grain structure. The high carbon content gives it performance characteristics such as high strength and hardness, while slightly reducing the difficulty of machinability and weldability.

Steel tubes under A513 are used in most cases exclusively for the manufacture of DOM tubes, which are used in the machinery, automotive and construction industries.

ASTM A513 Standard Specifications

ASTM A513 Dimensions

ASTM A513 covers a wide range of erw carbon and alloy steel pipes used as mechanical pipes. Mechanical pipes made from hot or cold rolled steel are produced in strict accordance with A513. At the same time, the shape also involves square, round, rectangular and shaped tubes.

  • Round tube: 0.500-2.00 inches
  • Square pipe: 0.500-1.500 inches
  • Thickness: 24 gauge to 12 gauge
    Other shapes and sizes are also available according to project requirements.

Pipes produced in accordance with the A513 specification also offer increased ductility through their tightly controlled carbon steel grades.

  • ASTM A513 1026
  • ASTM A513 4130

ASTM A513 Chemical Component

ASTM A513 is made of 1008-1015 steel, its main element is iron, but also contains trace amounts of carbon. This makes it the best choice for applications where tight dimensional tolerances and smooth surface finishes are required. In contrast, the A500 is made from higher grade steel, also known as A1085.

Compared to A513, A1085 has a higher carbon content and also contains a variety of elements such as silicon and manganese. As a result, the A513 has a higher load-bearing performance than the A513.

Performance Characteristics under ASTM A513 Standard

ASTM A513 Physical Properties

Tensile strength describes the value of the tensile stress that a material can withstand before breaking or completely failing.

The maximum tensile strength of the A513 carbon steel is determined by dividing the area of the steel by the stress applied to it, which is expressed in pounds or tons per square inch of material. The ability of the A513 to perform in practical applications, its tensile strength is regarded as a key evaluation criterion. The following is the tensile strength table for ASTM A513 carbon steel:

In the context of increasingly advanced technology and expanding application scope in the future, we have enough confidence that A513 standard will continue to promote the development of the pipeline material industry, bringing safety and reliable protection for engineering projects.

     FAQs:

1. What is the difference between grade A500 and A513?

The ASTM A500 rectangular tube is extremely durable, with a minimum yield strength of 50,000 psi, and it has been widely used in building support work.

A513 has a minimum yield strength of 30,000 psi, which makes it more widely used in commercial and consumer applications, such as lawnmower handles.

The Key Differences of ASTM A513 vs ASTM A500 are shown in the following table:

A513

A500

Tighter Dimensional Tolerances (ex: 2×2-0.083, Corner Radius is 5/64” to 0.125”)

Looser Dimensional Tolerances (ex: 2×2-0.083, Corner Radius max is 0.249”)

No Physical Requirements

Physical Requirements (Yield, Tensile, Elongation)

No Stenciling required

Stenciling (required for material with a 5” or larger side)

Easier to bend due to lower carbon content

Harder to bend due to higher carbon content

2. What is ASTM A513 Type 5 specification?
