Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
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: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 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 can I connect channel steel and round steel?
Can first welding a large circular steel plate and steel bar etc. in the channel to the end faces of the circular plate thickness should be more than 10mm, then the circular plate side angle steel and round steel bar to coincide welding, chamfering, need full welding between the two.
Q:Is HRB335 round steel or rib steel?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words.The numbers behind HRB represent the mechanical properties of the material they produce. The specific value is the yield strength of the material, sigma S (or Sigma P0.2). HRB335, indicating rebar with a yield strength of 335MPa.
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:12 of the diameter of the round steel can be M12 out of the thread is not
It depends on your material straight straight, generally should be right, you check the metric thread specification table, there is large size can be much, I think you are a little round a little better, so that you may get the car, do not appear to have a side material shortage phenomenon
Q:Why is the round bar bent?
Round steel with hooks the aim is to increase the bond between concrete and prevent the component in the tension will be reinforced. Therefore, round bars should be 180 degrees of hook, should set up 90 degree hook ribbed bar.
Q:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
