ASTM A500 is a standard specification published by ASTM International,a voluntary standards development organization to develop technical standards for materials, products, systems and services.
ASTM A500 covers cold-formed welding and seamless carbon steel tubes for welding of bridges and buildings, riveted or bolted structures, and round, square, rectangular, or special-shaped steel tubes for general structural purposes.
ASTM A500 steels have a density of approximately 7850 kg/m3 (0.284 pounds per cubic inch). The pipe is produced in welded and seamless dimensions with a circumference of 88 inches (2235 mm) or less and a specified wall thickness of 0.875 inches (22 mm) or less.
ASTM A500 Seamless Square Hollow Section Tube
ASTM A500 SHS Pipe is used in structural applications for its strength. The specification covers cold formed, welded and seamless carbon steel tubing for structural applications with round and shapes of Grade A, B, C or D. The A500 Grade B Square Tube is used for its known structural strength because of the geometric shape. The pipes come in 1/8 inches to 30 inches of nominal bore sizes.
According to the chemical composition, tensile strength and heat treatment, A500 cold bending pipe is divided into four grades (A/B/C/D).Square and rectangular yield strength requirements are higher than for round tubes.The minimum copper content is optional.Class D must be heat treated.

ASTM A500 Carbon Steel Mechanical Properties
Tensile strength refers to the amount of stretching stress a material can withstand before breaking or failing. The ultimate tensile strength of A500 carbon steel is calculated by dividing the area of the steel by the stress placed on it, which is expressed in terms of pounds or tons per square inch of material. Tensile strength is an important measure of A500’s ability to perform in an application.

FAQ:
Q: What are the advantages of ASTM A500 carbon steel structural pipe?
A: ASTM A500 Carbon Steel Structural Tubing provides several advantageous qualities that make it a highly sought after construction material for structural load bearing applications. Some of the most recognizable beneficial qualities that A500 Carbon Steel Structural Tubing provides includes:
excellent weldability,good machinability,can be cold worked,aesthetically pleasing.
Q:What are the typical uses of astm a500?
A:Typical uses of ASTM A500 are: structural support, building pillars, highway signs, oilfield services and communication towers, etc.
Note: seamless and welded pipe: The difference in the basic manufacturing method is obvious from the names. Seamless tube is extruded and drawn from a billet while welded tube is produced from a strip that is roll formed and welded to produce a tube.
