Description
(1) Low carbon steel Also known as mild steel, carbon content from 0.10% to 0.30% low carbon steel is easy to accept a variety of processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shafts and so on.
(2)Medium carbon steel Carbon steel with a carbon content of 0.25% to 0.60%. There are a variety of products such as killed steel, semi-killed steel, boiling steel. In addition to carbon, it may contain a small amount of manganese (0.70% to 1.20%).
(3) High carbon steel Often referred to as tool steel, carbon content from 0.60% to 1.70%, can be hardened and tempered. Hammers, crowbars,etc. are made of steel with a carbon content of 0.75%; cutting tools such as drill bits, wire taps, reamers, etc. are made of
steel with a carbon content of 0.90% to 1.00%.

Product Show
A36 is a carbon structural steel whose chemical composition and mechanical properties strictly conform to American ASTM standards. A36 steel bar mainly consists of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Iron constitutes more than 99% of the entire chemical composition. Its carbon content proportion is relatively high, around 0.2%, 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. Phosphorus and sulfur are low so that the steel bar has good welding performance and corrosion resistance. A36 steel bar 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.
