Round steel refers to the solid section for circular strip steel.Its specifications expressed as a number of mm in diameter, such as ""50"" indicates that the diameter of 50 mm round steel.Round steel hot rolling, forging and cold drawn three kinds.The specifications of the hot rolled round steel of 5.5 to 250 mm.5.5-25 mm small round steel are mostly with straight into bundles of supplies, commonly used for reinforcing steel bar, bolt, and various mechanical parts;More than 25 mm round steel,mainly used in the manufacture of mechanical parts and seamless steel tube billet.
Carbon steel according to the chemical composition (i.e., with carbon content) can be divided into low carbon steel, medium carbon steel and high carbon steel.According to the quality of the steel can be divided into ordinary carbon steel and high quality carbon steel.According to the purposes and can be divided into carbon structural steel, carbon tool steel.
The difference between the round steel and other steel: 1 appearance is not the same, round steel exterior circle of light, no lines without ribs, and other steel surface appearance has a groove or a rib, thus causing the cohesive force of small round steel and concrete, and the other the cohesive force of steel bar and reinforced concrete.2 ingredients are different, round steel (level 1) steel belong to the normal low carbon steel, more than other reinforcement for alloy steel.Three different intensity, low intensity of round steel and other steel high strength namely round steel have larger deformation before is pulled, and reinforced by other tensile deformation is much smaller.
