- Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
- Annealing: the annealing of hypoeutectoid steel workpiece heated to AC3 above 20 - 40 degrees heat after a period of time, furnace cooling (or buried in the sand or lime cooling) to 500 degrees Celsius in air cooling heat treatment process.
- Q:Embedded bolts M24 why use M25 round steel?
- 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,
- Q:Can steel bars be replaced by large screws in the concrete floor?
- In theory, how big a round steel will have to replace the large thread steel, and if it is cast, then still better to use thread steel, screw steel tensile resistance than round steel by strong
- 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:What's the difference between round steel and carbon bound steel?
- The composition is different, round steel (grade a steel) belongs to ordinary low carbon steel, carbon tie steel is mostly alloy steel.
- Q:Round bars and ribbed stirrups are much better
- The flexibility of hot rolled round steel bar is better than that of ribbed steel bar, and its fatigue stress amplitude is wide allowable. It is suitable for the components under dynamic load, as well as lifting rings, rings and lifting workpieces;
- Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
- Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
- Q:What kind of steel bars are used in general civil buildings?
- Steel is the HRB335, the diameter of 12 to 22, 25, 28, even 32, and then rough generally appear in the mass concrete construction, not commonly used, generally below 25 is commonly used in masonry structure in rural low level below 16 is most commonly used. Used as beams, columns, main bars and stand bars, etc.
- Q:Which is hard, round steel or screw steel?
- If the diameter is the same, of course, the rebar is of great hardness.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 is galvanized round bar?
- A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
