A36 Round Steel Bar Description<\/strong><\/b><\/h2>\n

A36 is a carbon structural steel whose chemical composition and mechanical properties\u00a0strictly conform to\u00a0American ASTM standards.\u00a0A36 steel\u00a0bar\u00a0mainly\u00a0consists\u00a0of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements.\u00a0Iron\u00a0constitutes\u00a0more than 99% of the entire chemical composition.\u00a0Its\u00a0carbon content\u00a0proportion is\u00a0relatively high,\u00a0around\u00a00.2%, ensuring that the steel has a certain hardness and toughness. The addition of silicon, manganese and other elements enhances the strength and toughness of steel.\u00a0Phosphorus and sulfur\u00a0are\u00a0low\u00a0so\u00a0that the steel\u00a0bar\u00a0has good welding performance and corrosion resistance.\u00a0A36 steel bar\u00a0is 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.<\/p>\n
