Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The same specification galvanized round steel, more than a round galvanized process, so galvanized round bar price = round bar cost + zinc + processing fee + three costs + wear and tear.
Q:Difference between forging and round steel
A forging is a process in which a metal is heated and shaped by plastic deformation or a desired compressive force is applied. This force is typically achieved by using a hammer or pressure. The casting process constructed a fine grain structure and improved the physical properties of the metal. In the practical use of parts, a correct design allows the particles to flow in the direction of the main pressure.
Q:Is round bar steel?
For example, the steel structure material is Q235B, and the steel bar is HPB235. Although the strength is the same, the production process is still different, the requirements of higher steel bar, there is a new specification more stringent.
Q:How many tons of pressure can the round steel of 70 inches bear?
If the steel will generally approximate compressive strength considering tensile strength, even if is only 4 tons / square centimeters, each round cross section of 26 mm diameter is 5.3 cm, maximum 5.3*4 about 20 tons of pressure, the actual use should take into account the safety factor;
Q:Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
Q:What is round steel?
More than 25 mm round steel, mainly used in the manufacture of mechanical parts or between round steel and other steel seamless steel tube blank: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength.2 other components of steel and concrete are not the same, round (a steel) belongs to the ordinary low carbon steel, alloy steel reinforced many other.3 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 small steel however, plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The general anchor bolt is made of Q235 steel, which is round. Rebar (Q345) strength, do nut thread no light round easily.
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:Can the same grade steel instead of round bar be ok?
Tolerable。1. grades of steel are different (chemical composition is different). Round steel (HPB235) is carbon steel, steel is Q235; thread steel is low alloy steel; HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;
Q:20# difference between round bar and A3 round bar, can they be used separately?
20# rounds are plain carbon steel, as well as 10#, 20#, 45#, etc.A3 round bar is Q235, grade is ABCDE, etc., commonly used is Q235BIn use performance, 20# hardness is strong, but the elasticity is bad, welding performance is poorA3 hardness is less, but good elasticity, good welding performanceAs for specific can not be replaced, mainly depends on the use of places.
