- 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.
- A36 steel is made through a hot-rolling process, meaning it's 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.
- 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.
