Round steel refers to the solid section for circular strip steel.Its specifications expressed as a number of mm in diameter, such as ""50"" indicates that the diameter of 50 mm round steel.Round steel hot rolling, forging and cold drawn three kinds.The specifications of the hot rolled round steel of 5.5 to 250 mm.5.5-25 mm small round steel are mostly with straight into bundles of supplies, commonly used for reinforcing steel bar, bolt, and various mechanical parts;More than 25 mm round steel,mainly used in the manufacture of mechanical parts and seamless steel tube billet.

Carbon steel according to the chemical composition (i.e., with carbon content) can be divided into low carbon steel, medium carbon steel and high carbon steel.According to the quality of the steel can be divided into ordinary carbon steel and high quality carbon steel.According to the purposes and can be divided into carbon structural steel, carbon tool steel.

The difference between the round steel and other steel: 1 appearance is not the same, round steel exterior circle of light, no lines without ribs, and other steel surface appearance has a groove or a rib, thus causing the cohesive force of small round steel and concrete, and the other the cohesive force of steel bar and reinforced concrete.2 ingredients are different, round steel (level 1) steel belong to the normal low carbon steel, more than other reinforcement for alloy steel.Three different intensity, low intensity of round steel and other steel high strength namely round steel have larger deformation before is pulled, and reinforced by other tensile deformation is much smaller.

Q:What is the difference between steel and flat steel, round steel and steel?
On the whole, the square section is square, flat section is rectangular, steel surface after finishing the round steel or steel wire (also called steel, silver bar).
Q:What is the difference between strip steel and round steel? Where are they mainly used?
Strip steel is a kind of narrow and long steel plate produced by various rolling mills to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.Strip steel is widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades, hardware and blades.
Q:What is the difference between 40Cr round steel and 40Cr steel forgings?
Generally speaking the 40Cr steel is a kind of hot rolled steel (rarely cold). The need for heating the material before hot rolling process is or rolled, usually heated to above the recrystallization temperature, then condensation formed after the bar, of course I say is very simple, there are many steps.
Q:What's the difference between round steel and other steel bars?
Different appearance, round steel appearance garden, no grain without rib, other steel surface has carved or ribbed. This causes the round bar and concrete bonding force is small, and other steel and concrete bonding force
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:Excuse me and steel disc round what is the difference?
Wire rod refers to the hot-rolled steel bar of 5-22mm diameter or the special-shaped steel of this section. As a result of wire rod delivery, it is also known as wire rod.
Q:How to make the round welds on flat steel flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:The problem of dowel bars on concrete pavements?
The dowel bar is arranged according to the transverse contraction joint and expansion joint set, meaning that a transverse contraction joint and expansion joint place dowels, are not plate must be set. In general, each 200m set a expansion joint, or other road intersection, and bridge connecting point must be set up.
Q:20# difference between round bar and A3 round bar, can they be used separately?
The former belongs to low carbon steel, and the latter belongs to iron.The mechanical properties of the two are completely different, and they can not be interchanged if they are technically required
Q:Why do I use the M25 round bar for the embedded bolt M24?
Such as using 24 of the round steel, worried about the surface quality of steel when the processing can not be nominal diameter 24 of the standard thread, of course, the election is too large and wasteful, so generally choose 25 of the round bar,
