Q:Why is round steel more expensive than thread steel?
Threaded steel should be used in the construction field, there are generally two, three grade steel, grade HRB335, HRB400 also has four grades, HRB500 thread steel. Steel is divided by tolerance standard of gb. You say there is no comparable price between round bar and screw thread
Q:Are the bolts for the round bar or round steel?
The utility model relates to a pair of bolts which are used for drawing between the inner and the outer formwork of the wall when the beam and the column template are set. The bolt under concrete lateral pressure and other loads, ensure the spacing inside and outside the template can meet the design requirements, but also the template and its support structure fulcrum, so the impact on the overall arrangement of bolt, the template structure stiffness and strength greatly.
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:Difference between cold drawn round steel and round steel
The free torsion rigidity of hot rolled steel is higher than that of cold rolled steel, so the torsion resistance of hot rolled steel is better than that of cold rolled steel.
Q:What is the difference between a circle and round steel continuous casting
Round steel drawn from a continuous casting is called a round billet; the rolled round steel is called a bar.
Q:How to make the round welds on flat steel flat and qualified?
On both sides of the steel and welded steel plate, each side of the weld length of 5 times the diameter of reinforcement, welding seam should be welded into a convex arc that is.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:How about tempering No. 45 round bar?
Quenched and tempered steel has two major categories: carbon quenched and tempered steel and alloy quenched and tempered steel. Carbon steel or alloy steel, the control of carbon content is relatively strict. If the carbon content is too high, after quenching and tempering the strength of the workpiece is high, but the toughness is not enough, such as carbon content is too low, toughness and lack of strength. In order to make the quenched and tempered parts get good comprehensive performance, the total carbon content is controlled at 0.30~0.50%.
Q:What is the tensile strength of Q235 round steel?
Level 1, surface shape, light circle, strength code R235, grade Q235, carbon content 0.14%-0.22%. Silicon content 0.12%-0.30%. Manganese content 0.30%-0.65%, phosphorus content is equal to less than 0.045%, sulfur content is less than or equal to 0.050%,
Q:What is galvanized round bar?
Galvanized round bar generally refers to the wiring used for lightning protection in construction and installation. It is made of ordinary round steel (usually 8mm to 12mm diameter) and protected by electro galvanized protection layer. Galvanizing, differentiation, plating and electroplating, cold galvanizing and hot galvanizing etc..
