Q:What is the content ratio of the screw steel and manganese steel?
The standard type of high manganese steel Mn13 steel and Hadfield steel, high manganese steel castings in China National Standard (GB/T5680-1998) grade: ZGMn13-1, ZGMn13-2, ZGMn13-3, ZGMn13-4, ZGMn13-5; ASTM (ASTMA128/A128M-1993) standard austenitic manganese steel casting steel are: ASTM-A (UNS-J9110.
Q:What is thread steel for?
1. nominal diameter range and recommended diameterThe nominal diameter of the thread steel is from 6 to 25mm, and the nominal diameter of the standard steel is 6, 8, 10, 12, 14, 16, 20, 25,, 32, 40 and 50mm.Allowable deviation of surface shape and dimension of 2. ribbed steel discThe ribbed steel bars with ribbed threads shall meet the following basic requirements:The angle between the transverse ribs and the axis of the steel disc should not be less than 45 degrees. When the angle is not greater than 70 degrees, the direction of the cross section of the thread steel is opposite to that of the upper rib on both sides;The transverse rib and the spacing l shall not be greater than 0.7 times the nominal diameter of the steel;The angle between the sides of the transverse rib and the surface of the threaded steel shall not be less than 45 degrees;The sum of the gap (including the width of longitudinal ribs) between the ends of the cross bar and the end of the cross bar of the threaded steel shall not be greater than 20% of the nominal circumference of the thread steel;When the rebar nominal diameter less than 12mm, the relative rib area should not be less than 0.055; the nominal diameter of 14mm and 16mm, the relative rib area should not be less than 0.060; the nominal diameter is more than 16mm, the relative rib area should not be less than 0.065.
Q:Are steel bars used more in high-rise buildings or steel?
Look at the architectural design requirements and seismic grade, light steel reinforcement is mainly stirrups, columns, beams, shear walls generally use thread steel, plate bars and distribution bars are generally cold and twisted steel bars
Q:What is the difference between rebar bolts and steel bars?
This question can only be answered: "material should not be compared to components.". Insist on saying the difference, one is the material, and the other is the component.You may ask the difference between soil nail and anchor bar, but the topic is not. I shall be glad to answer another question!
Q:What does it mean to have 22 4GJ on the threaded steel?
4GJ22 these are the basic information of reinforcement, equivalent to the identity card information. The steel plant on behalf of grade four steel (HRB500) GJ is Hangzhou iron and then the nominal diameter is 22.
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:Why is the threaded steel thread?
Steel is commonly known as hot rolled ribbed bar, belonging to the small steel steel, mainly used for steel reinforced concrete structure frame. In use, some mechanical strength, bending deformation property and welding performance are required.
Q:Why can't grounding steel be used?
When the thread steel is grounded, the contact with the soil is not dense, and the grounding resistance value is increased
Q:Is cold-rolled ribbed steel bar thread steel?
I haven't heard of cold-rolled steel. Cold rolling is called thin plate
Q:What's the difference between finish rolling thread steel and ordinary thread steel?
To say the difference between the new bridge finish rolling thread steel and ordinary thread steel main difference between finish rolling thread steel: mainly used for high strength, difference is mainly different strength, chemical composition is not the same:Finish rolling thread steel is prestressed steel, and its strength is higher than ordinary thread steel.
