Q:How to calculate the theoretical elongation of finishing thread steel?
Rebar is a kind of special bar with discontinuous external thread. The steel bar can be connected or anchored at any section with a connector or anchor with internal thread.
Q:What is the carbon content of thread steel?
It is understood that carbon is the main element determining the performance of steel, because changes in carbon content directly lead to changes in crystal structure. With the increase of carbon content, the strength and hardness of the threaded steel increase, while the plasticity and toughness decrease. When the carbon content is more than 1%, the strength of the rebar decreases. The increase of carbon content also reduces the weldability and corrosion resistance of steel, and increases the cold brittleness and aging tendency of steel.
Q:How much is the minus difference per ton of thread steel?
H, R, and B are the first letters in English for hot-rolled (Hotrolled), ribbed (Ribbed) and reinforced (Bars) three words. Hot rolled ribbed bar is divided into HRB335 (old No. 20MnSi), HRB400 (20MnSiV, 20MnSiNb, veteran, 20Mnti), HRB500 three brands.
Q:12 of the threaded steel can replace 16 of the screw steel? But the same proportion. Thanks
Now Tianjin Tiantai into 12 of the price is 3900 yuan a ton, 16 tons of steel a price is 3850 yuan. 12 of thread steel is 50 yuan more expensive than 16 thread steel.
Q:Which is more expensive, rebar or round steel? Which is your business opportunity, such as thread steel and round bar?
The two thread steel and round steel, which will be more expensive, steel and round steel prices now are soaring, steel prices per ton in 4300 yuan / ton, quality steel grade three Beijing qianshengcheng price is in 3950-4200 yuan / ton.
Q:Grade 1, grade three, grade two, steel, wire rod, round bar
Wire is a wire, usually refers to the use of "high speed non-twist wire rod rolling mill, ordinary common low carbon steel, hot-rolled wire torsion free cooling (ZBH4403-88) and the high quality carbon steel, hot-rolled wire rod without torsion cold control (ZBH44002-88).
Q:Now, the two project is to use rebar or rebar?
Suggest a slightly larger span of the floor, do not use round steel bar, or the use of thread steel bar, and then with anti crack 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 quality difference between round bar and screw steel?
Different shape. The outer surface of the round steel is smooth; the outer surface of the spiral steel has a spiral rib. 2. different production standards. In the current standard, round bar that HPB235 grade steel, and its production standards are "hot-rolled smooth steel reinforced concrete" (GB13013); rebar generally refers to HRB335 and HRB400 grade steel, its production standard is "the reinforcement of concrete hot rolled ribbed bar" (GB1499). 3. different strength. The design strength of round steel (HPB235) is 210MPa; the strength of thread steel is higher than that of round bar; the design strength of HRB335 is 300MPa; the design strength of HRB400 is 360MPa.
Q:Like a steel rebar and wire spiral, is the same? What's the difference?
Generally, most of the diameter of thread steel in 10-34mm, while the general disk diameter less than 10mm, but also because of too small so often set up the price must be placed, what will be a little expensive disk. A house built of steel plate with the words to be used for different purposes. The price of concrete is not clear.
