What Is A36 Material
A36 is the designation assigned by ASTM International to the most commonly used steel alloy in the United States. It is a good general purpose steel and easily welded through normal processes, such as stick, MIG and oxyacetelyne welding.
Characteristics
A36 steel is a mild, or low-carbon steel. It is 99 percent iron and contains small amounts of carbon, manganese, copper, phosphorus and sulfur. Its tensile strength is 58,000 to 79,800 psi, while its yield strength is 36,300 psi and its elongation is 20 percent.
Uses
A36 steel is made through a hot-rolling process, meaning its heated to a little above its recrystallization temperature and squeezed between rollers, and has a somewhat rough surface. It is available in the form of plates, rods, bars, angles, channels, H-beams and I-beams.
Expert Insight
ASTM International is the organization that develops standards, test methods, guides, specifications and practices in a number of fields, including construction and other materials, consumer products and medical devices. It also provides training for industry on specific standards. It was formerly known as the American Society for Testing and Materials.
