Q:What kind of material is the first round steel?
Standard Specification for hot rolled round steel is 5.5-250 mm. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Solution treatment: the alloy can be dissolved in various phases, strengthening solid solution, improving toughness and corrosion resistance, eliminating stress and softening, so as to continue processing and forming.
Q:How many tons of pressure can the round steel of 70 inches bear?
As the diameter of about 11.5 cm diameter 180 cm long in the middle of the force which kind of force will be smaller if the curvature is hollow capability hollow wall thickness to achieve much greater strength than to solid
Q:What's the difference between bar and round bar?
Bars can be either round or square or six sides.Another argument is that bars usually refer to short ones. The rounds are not cut, usually 6 meters long supply.
Q:What is the mechanical properties of No. 40 round bar?
There are 20 kinds of steel classification: carbon steel, alloy steel, carbon structural steel, special purpose and so on. Look at the questions this afternoon and find out about the books. Which type of steel do you ask? This is not clear, I gave up the answer, and then I see your this question.
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:How do you know the diameter and weight of a round bar?
Round is a round, the quality of its G (in grams) is equal to the volume multiplied by the density of 7.85 steel, and its volume is equal to the bottom area multiplied by the degree of L (in cm), then the bar diameter of d=4 * G / L / 7.85 / 3.14 value points
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.
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
When the mechanical component is installed on the concrete foundation, one end of the bolt is J and L shaped, and is embedded into the concrete.
Q:The 8 thread can replace the beam stirrups by steel
First class steel is HPB235, that is, yield strength is 235mpa, elongation of grade steel is much larger than grade two steel, and the scientific name of grade two steel is HRB335, that is, yield strength is 335mpa, and grade two steel is higher than first grade steel. But also a high level of brittle than steel, as in seismic zone two structure beam is not replaced.
