Product Parameters

round steel
Round steel refers to a solid strip steel with a circular cross section. [1] Its specifications are expressed in millimeters of diameter. For example, "50" means round steel with a diameter of 50 millimeters.
The difference between round steel and other steels		1, the appearance is not the same, round steel appearance is smooth and round, no grain and no rib, and other steel bars have carved lines or ribs on the surface, which causes the bonding force between round steel and concrete to be small, while other steel bars have large bonding force with concrete. 2, the composition is different, round steel (first-class steel) belongs to ordinary low-carbon steel, and other steel bars are mostly alloy steel. 3, the strength is not the same, round steel strength is low, other steel strength is high, that is, round steel with the same diameter can bear less tension than other steel bars, but the plasticity of round steel is stronger than other steel bars, that is, round steel has greater deformation before being pulled off, while other steel bars have much smaller deformation before being pulled off.
Classification of round steel		Round steel is divided into hot rolling, forging and cold drawing. The specification of hot rolled round steel is 5.5-250 mm. Among them, 5.5-25 mm small round steel is mostly supplied in bundles of straight bars, which are often used as steel bars, bolts and various mechanical parts; Round steel larger than 25mm is mainly used for manufacturing mechanical parts or seamless steel tube blanks.
Classification of chemical composition of round steel
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (that is, carbon content).
low-carbon steel		Also known as mild steel, low-carbon steel with carbon content from 0.10% to 0.30% is easy to accept various processes such as forging, welding and cutting, and is often used to manufacture chains, rivets, bolts, shafts, etc.
medium carbon steel		Carbon steel with carbon content of 0.25% ~ 0.60%. There are killed steel, semi-killed steel, boiling steel and other products. Besides carbon, it can also contain a small amount of manganese (0.70% ~ 1.20%). According to the product quality, it is divided into ordinary carbon structural steel and high-quality carbon structural steel. Good hot working and cutting performance, poor welding performance. Strength and hardness are higher than those of low carbon steel, but plasticity and toughness are lower than those of low carbon steel. Hot rolled and cold drawn materials can be used directly without heat treatment, or they can be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The highest hardness that can be achieved is about HRC55(HB538) and σb is 600~1100MPa. Therefore, medium carbon steel is widely used in various applications with medium strength level, except as building materials, it is also widely used to manufacture various mechanical parts.
high-carbon steel		Often called tool steel, the carbon content ranges from 0.60% to 1.70%, which can be hardened and tempered. Hammer, crowbar, etc. are made of steel with carbon content of 0.75%; Cutting tools such as drills, taps and reamers are made of steel with carbon content of 0.90% to 1.00%.
