A36 steel is a type of carbon steel commonly used in construction and manufacturing. It is known for its good weldability, machinability, and strength, making it suitable for a variety of structural applications. A36 steel typically has a yield strength of 36,000 psi, which means it can withstand significant stress before deforming. This steel is often used in the fabrication of beams, columns, and plates, as well as in the production of various machinery and equipment. Its versatility and cost-effectiveness make it a popular choice in industries such as construction, automotive, and shipbuilding.
