ASTM A500/A500M

ASTM A500/A500M carbon steel tubing is a standard specification for cold-formed, welded and seamless carbon steel structural tubing in round, square and rectangular shapes. ASTM A500 is the most common specification in North America Hollow Structural Sections (HSS).

ASTM A500/A500M specification covers cold-formed welded and seamless carbon steel tubing in round, square, rectangular, and “special” shapes for welded, riveted, or bolted construction applications, as well as for general structural purposes.

Round and shaped steel cold formed welded and seamless carbon steel structural pipe.


Specifications:

OD :10.3-820 mm

Wall Thickness: 0.8 to 75 mm

Length: 6m

In addition, based on customer requirements, which can supply other grades and specifications of steel pipe.

ASTM A500/A500M carbon steel structural tubing is only manufactured from materials that match the criteria for carbon steel. The chemical composition for ASTM A500/A500M is mostly iron with added carbon, manganese, phosphorus, sulfur, and copper.

ASTM A500/A500M 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 ASTM A500/A500Mcarbon 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 ASTM A500/A500M’s ability to perform in an application.ASTM A500/A500M carbon steel’s tensile strength is described in the chart below.
