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:The 8 thread can replace the beam stirrups by steel
That's fine, but it's not necessary. It's more expensive. Of course, there's no substitute for steel bars on the site.
Q:What is the difference between 40Cr round steel and 40Cr steel forgings?
But 40Cr forgings are objects that are subjected to pressure by plastic deformation to shape a desired shape or suitable compressive force. (usually done by using hammers or pressure).
Q:How do you know the diameter and weight of a round bar?
The weight divided by the length is the bottom area of 2, Wu R - is the bottom area. The diameter is equal to 2R
Q:Why can't the grounding device be replaced by steel bar instead of round steel?
The mechanical strength of the steel thread is destroyed. Because the supporting point is only the ground, it is easy to cut the steel directly if the thread is not vertical. Therefore, we need to use angle iron, steel pipe or smooth steel round bar.
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:What's the difference between round steel and other steel bars?
The composition is different, round steel (grade a steel) belongs to ordinary low carbon steel, other steel bars are alloy steel
Q:Difference between round bar and threaded steel in use.
The rebar is much higher than the ordinary, and the low carbon steel rounds are much higher. The heat treated steel is much stronger than the low carbon round steel, nearly twice or even higher.
Q:What is the tensile strength of Q235 round steel?
According to the national standard of GB 13013-1991 reinforced hot rolled round steel bars,Q235 reinforcement
Q:20 round bars are of several grades
20 round bars may be grade two steel.
