Product Desciption
1. Divided by process: round steel is divided into three types: hot rolled, forged and cold drawn.The specification of hot-rolled round steel is 5.5-250 mm
2. According to chemical composition: carbon steel (carbon content) can be divided into low carbon steel, medium carbon steel and high carbon steel
(1) Mild steel
Mild steel, with carbon content ranging from 0.10% to 0.30%, is easy to accept various processing such as forging, welding and cutting, and is often used to make chains, rivets, bolts, shafts, etc.
(2) Medium carbon steel
Carbon steel with a carbon content of 0.25% to 0.60%. There are many products such as killed steel, semi-killed steel, rimmed steel and so on. In addition to carbon, it can also contain a small amount of manganese (0.70% to 1.20%). According to product quality, it is divided into ordinary carbon structural steel and high-quality carbon structural steel. Strength and hardness are higher than low-carbon steel, while plasticity and toughness are lower than low-carbon steel. The highest hardness that can be achieved is about HRC55 (HB538), and σb is 600~1100MPa. Medium carbon steel is the most widely used, in addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.
(3) High carbon steel
Also known as tool steel, the carbon content ranges from 0.60% to 1.70%, which can be hardened and tempered. Hammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, reamers, etc. are made of steel with a carbon content of 0.90% to 1.00%.
3. According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel.
4. According to the purpose, it can be divided into carbon structural steel and carbon tool steel. Carbon structural steel is divided into 5 grades according to the yield strength of steel: Q195, Q215, Q235, Q255, Q275
5.Round steel material: Q195, Q235, 10#, 20#, 35#, 45#, Q215, Q345, 12Cr1Mov, 15CrMo, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo, GCr15, 65Mn, 50Mn , 50Cr, 3Cr2W8V, 20CrMnTi, 5CrMnMo, etc.

PRODUCT DISPLAY
Round steel refers to a solid long steel with a circular cross section. Its specifications are expressed in millimeters of diameter. Round steel is divided into three types: hot-rolled, forged and cold-drawn. The specification of hot-rolled round steel is 5.5-250 mm. Among them: 5.5-25mm small round steel is mostly supplied in straight strips, often used as steel bars, bolts and various mechanical parts; round steel larger than 25mm is mainly used to manufacture mechanical parts or seamless steel tube billets.
