A36 Carbon Steel Bar - Technical Overview & Specifications
A36 is a low-carbon steel containing trace amounts of manganese, phosphorus, sulfur, silicon and other elements such as copper. A36 has good weldability and high yield strength, and is the most specified structural steel plate by engineers. ASTM A36 is most commonly manufactured as a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, as well as for general structural purposes. Due to its lowest yield point, A36 can be used to design lighter-weight structures and equipment, and provide good weldability.
