Product specifications
Round Steel
Plain carbon structural steel, also known as ordinary carbon steel, has a wide range of carbon content, properties and restrictions on the content of phosphorus, sulphur and other residual elements. According to the delivery guarantee conditions are further divided into three categories: Class A steel (Class A steel) is the guarantee of mechanical properties of steel. Class B steel (Class B steel) is the guaranteed chemical composition of the steel. Special category steel (C steel) is a steel that guarantees both mechanical properties and chemical composition, and is often used in the manufacture of more important structural components.
According to the carbon content of the composition is divided into: low carbon steel, medium carbon steel and high carbon steel; according to the use is divided into: carbon structural steel and carbon tool steel. Round steel is a long, solid steel bar with a circular cross-section, which is common in construction and hardware accessories such as round steel bars for concrete and solid seamless steel pipes. Round steel is classified according to the process: hot rolled round steel, forged round steel and cold drawn round steel.
Some carbon structural steels also add trace amounts of aluminium or niobium (or other carbide-forming elements) to form nitride or carbide particles to limit grain growth and make the steel stronger, saving steel. To adapt to the special requirements of professional steel, the chemical composition and properties of ordinary carbon structural steel to adjust, thus developing a series of ordinary carbon structural steel professional steel (such as bridges, construction, reinforcing steel, pressure vessel steel, etc.).

Product Details
According to the different amount of manganese, and can be divided into ordinary manganese content (0.25 ~ 0.8%) and higher manganese content (0.7 ~ 1.0% and 0.9 ~ 1.2%) two steel groups. Manganese can improve the hardenability of steel, strengthen the ferrite, improve the yield strength, tensile strength and wear resistance of steel. Usually in the high manganese content of the steel grade after the additional mark "Mn", such as 15Mn, 20Mn to distinguish from the normal amount of manganese content of carbon steel.
Round steel has a smooth appearance and no grain, so the bond between round steel and concrete is small, and in construction it is necessary to choose steel with grain to be more solid; round steel bears less tension than steel, but its plasticity is stronger than that of steel.
The main materials of round steel: 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.
Applications
Round steel is mainly used for the manufacture of mechanical parts or as seamless steel billets. Alloy structural steels can be used to make parts with higher steel strength and larger cross-sections, such as large gears and rear axles. Medium carbon steels have temper brittleness and superheat sensitivity and are prone to cracking during quenching and can be used to make parts that work under heavy load conditions, such as crankshafts, axles and piston rods. High-carbon steel can be used to make tools that are not subject to shock loads, have low cutting speeds and no heat in the cutting edge, such as lathes, planers' tools and drills, etc.
