Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
The general situation is not possible, but sometimes as stirrup time, and has little effect on the structure, if 12 reinforced with missing a few, but not on the main force position is possible, sometimes supervision is not allowed.
Q:The two project is to use rebar or rebar?
It is recommended to use thread steel as far as possible, because the bonding force and holding force of the thread steel is better than that of the round steel, and it is generally known that the tensile pulling force of the round steel is relatively poor.
Q:Requirements for groove welding of grade 22mm round steel and manual arc welding
If not on the lathe, in the groove on the round bar with gouging or cutting gun, docking form X type double sided bilateral docking, blunt edge 2mm root gap 2mm welding, welding side sincere one or two seam, flip the workpiece on the other side of a full weld groove, flip weld residual,
Q:What is the reason that the diameter 130-45 round steel will break after welding?
You say this is a better situation, generally in a few days after welding on the crack, the most afraid of the key parts, to be a major accident. No. 45 steel can not be welded, such as welding, it is necessary to preheat before welding and after welding heat treatment.
Q:Will the theoretical weight of thread steel and round steel be the same?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:45# what are the main rounds for?
45# round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter
Q:Which steel wire is the same diameter as round steel more resistant to breaking?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm of small round bars, mostly straight line bundles of supplies, commonly used as steel, bolts and various mechanical parts; more than 25 millimeters of round steel.
Q:Is round steel round steel?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.
Q:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
The main differences are in mechanical properties. Forged round steel is used in the processing of some special performance requirements. Round steel three processing methods are more common, should be very wide surface.
Q:Which is hard, round steel or screw steel?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets
