What is a round steel it? Round steel refers to a circular section solid strip steel. Diameter mm, its specifications, such as "28" means that the diameter of 28mm round steel. Round steel classification, as well as use it? The round bar is divided into hot-rolled bar, forged round bar and cold drawn round three. Hot rolled round steel specifications for the 5.5-250mm. :5.5-28mm round steel mostly straight into bundles supply, commonly used for mechanical parts; greater than 28mm round steel, mainly used in the manufacture of mechanical parts or seamless pipe billet. Round steel What kind of material? Round steel Material: 10 #, 20 #, 35 #, 45 #, Q235, 304,316,20 of Cr, 40Cr, 20CrMo, 35CrMo, 42CrMo, 40CrNiMo of GCr15, 50Mn, 50Cr, 3Cr2W8V, 20CrMnTi such as round bar and rebar The difference is where? 1 appearance, round steel exterior light circular pattern without rib the rebar surface appearance sculptured or rib, and so cohesive force caused by round steel and concrete, rebar and concrete stick force composition. 2 is not the same intensity, low intensity round steel, high strength rebar compared, that is the same size as the diameter of the round bar and rebar, round steel can withstand tension than rebar, round steel plasticity is stronger than rebar , i.e. round bar before pulled off a large deformation, while the rebar to be pulled off before the deformation smaller. Round steel refers to a circular section solid strip steel. Their specifications, such as "50" indicates that of 50 mm diameter round bar with a diameter of a few millimeters. The round bar is divided into hot-rolled, forged and cold drawn three. Hot rolled round steel specifications 5.5-250 mm. Most of the 5.5 - 25 mm round bar straight into bundles supply, commonly used for reinforcement, bolts and various mechanical parts; greater than 25 mm round steel, mainly used in the manufacture of mechanical parts or seamless steel pipe billet. Low intensity of round steel, other steels, high strength, and that is the same as the diameter of the round steel than other reinforced round steel can withstand tension than other reinforced, but the round steel plasticity than other reinforced, that is, in the round steel pulled off in front of a large deformation, and other reinforced pulled off before the deformation is much smaller.
