A36 Round Steel Bar
A36 is a low carbon steel that contains trace amounts of manganese, phosphorus, sulfur, silicon and copper, among other elements. A36 has good welding performance and high yield strength, and is the structural steel plate most specified by engineers. ASTM A36 is most commonly manufactured into a variety of structural steel parts. This grade is used for welded, bolted or riveted construction of bridges and buildings, and for general structural purposes. Due to its lowest yield point, A36 can be used to design lighter weight structures and equipment and provides good weldability.
