Q:Can I use steel bar instead of steel bar?
The substitution principle of steel bars is equal section substitution and equal strength substitution. Therefore, we can not use round steel instead of thread steel.
Q:What is the difference between 40Cr round steel and 40Cr forging parts?
The utility model has the advantages of high strength and good plasticity, and is suitable for making important parts with large force and high requirement.The properties of forgings are superior to those of ordinary ones.
Q:Why is it better to use round steel than flat steel in lightning protection?
In the construction of lightning protection, both round bar and flat steel have different uses. Flat steel is generally suitable for horizontal connection between vertical grounding poles for lightning protection. Round steel is suitable for lightning protectionThe guiding line and connected with lightning. The roof, all of the junctions are connected by welding requirements do not exist, what striking issues... The technical norms of the state said so, does not have what good and bad problem
Q:Is the shear wall concealed column stirrup steel or round steel?
Now the shear walls, columns and stirrups are basically round steel bars, and their requirements are as follows: 6.5~12 mm in diameter steel bars, most of the reel into a disk; 12~40 mm in diameter, usually 6~12 meters long straight bar. I grade steel (Q235 steel) are rolling for smooth circular section, supply form of material, diameter of not more than 12mm, the length is 6m~12m.
Q:Could you tell me what is the difference between steel pipe and round steel?
Widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:How to determine the welding seam height of steel plate and steel bar?
If the end of the vertical plane and the steel plate welding, welding angle as the bar diameter and the general welding height is 0.7 times the diameter of the arc can be reinforced; if the length direction of the surface of steel plate and steel welding, 2 side fillet weld cracks in the welded steel plate and steel between the full and round steel weldment the maximum diameter of arc phase can be flat.
Q:What's the difference between round steel and other steel bars?
Strength is not the same. The low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in tensile deformation is the former is much smaller.
Q:Is there a steel bar of 6 diameter on the market?
Reinforced concrete (Rebar) is used for reinforced concrete and prestressed reinforced concrete steel, its cross section is round, sometimes with rounded square.
Q:Is round steel bar round steel?
Yes.From the shape of points for the light round steel, crescent steel, rebar.From the strength of reinforcement is divided into one level (235), two (335), three (435), four (435)Cold drawn from the production process (first tensioning and long pull method), cold and so on
Q:Is there any technique for welding round steel?
The welding position is horizontal fillet welding, to control the size of the weld pool of available elliptic transport method the molten iron is brought up, and then try to consider the position of welding welding (a little more than half of small to)
