Steel profile round steel

  Round steel product introduction
Round steel refers to the long solid steel bar with round cutting anchor
Its specification is expressed in millimeters of diameter, such as & ldquo; 50”
That is, round steel with a diameter of 50 mm
Round steel is divided into hot rolling, forging and cold drawing
Gauge for hot rolled round steel
The grid is 5
5-250mm
Among them, small round steel of 5
5-25mm is mostly supplied in bundles by straight bars, which is often used as steel
Steel bars, bolts and various mechanical parts; Round steel larger than 25mm is mainly used for manufacturing mechanical parts or seamless steel
Steel pipe blank

Round steel parameters
Round steel specification: & phi; 6，Φ 18，Φ 20，Φ 75, etc
Material: 45#, stainless steel, plain carbon
Weight calculation formula: w = 0
006165 & times; d× D = diameter mm
Differences between round steel and other reinforcement:
1
The appearance of round steel is different
The appearance of round steel is smooth and round, without lines and ribs
The appearance of other reinforcement surfaces is engraved or ribbed, which
As a result, the bond between round steel and concrete is small, while the bond between other reinforcement and concrete is large

2
The composition is different
Round steel (grade I steel) belongs to ordinary low carbon steel, and other reinforcement is mostly alloy steel

3
The strength is different
The strength of round steel is low and that of other steel is high, that is, round steel with the same diameter and size is different from other reinforcement
In contrast, round steel can bear less tension than other reinforcement, but the plasticity of round steel is stronger than other reinforcement, that is, round steel
Steel has large deformation before being pulled off, while other reinforcement has much smaller deformation before being pulled off
