 42crmo steel round bar: round bar refers to the circular cross-section of a solid bar of steel. Mm of diameter, its specifications, such as "50" means that the diameter of 50 mm round bar. The round bar is divided into hot-rolled, forged, and cold drawing three. Hot rolled round steel specifications of 5.5-250 mm. :5.5-25 mm round bar is mostly straight into bundles of supplies, commonly used to make steel bars, bolts and various mechanical parts; greater than 25 mm round steel, mainly used in the manufacture of mechanical parts or seamless steel pipe billet round steel and reinforced the difference: an appearance is not the same as the light circle round bar shape, no pattern of rib, the other steel surface appearance Etched or rib would have resulted in a small round steel and concrete bond strength, the bond strength of steel bars and concrete. two ingredients are not the same, round steel (steel) belonging to the ordinary low carbon steel, other reinforced multi-alloy steel. 3 strength is not the same. low intensity of round steel, other steel high strength namely the diameter of the same size as the bar compared with other steel bar, round bar can bear the tension than other Reinforced small, round steel plasticity than other reinforced round bar pulled off before a large deformation , while the other reinforced pulled off before the deformation is much smaller.
