Q:What is the difference between grade two and three grade steel?
But from the definition we can see more of the same point, all belong to the common low alloy hot rolled ribbed steel bars; belong to (usually said that the rebar); can be used for engineering in reinforced concrete structure.
Q:Is the theoretical weight of threaded steel and round steel the same?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:What kind of steel is carbon steel in threaded steel?
Carbon steel. Carbon content of 0.06-0.22%, less than 0.25% is the most common. Of low carbon steel, each of which indicates the minimum yield point of the steel at a thickness of less than 16mm. Compared with high quality carbon steel, carbon content, range of performance, and content of phosphorus, sulfur and other residual elements are wider.
Q:Two grade steel and three grade steel difference, the construction of the use of thread steel in general how to use the level?
The main difference is the intensity, according to the design and construction requirements to determine the level of use
Q:Is the finish steel 3 grade steel?
The prestressed concrete thread reinforcing bar (also known as finishing thread reinforcing bar) is a kind of bar with big diameter, high strength and high dimension precision, which is rolled on the whole steel bar. The steel bar is screwed at any cross section with a connector with an internal thread to connect or screw on the threaded nut for anchoring. The fine rolled rebar is widely used in large water conservancy projects, continuous beams and large frame structures in industrial and civil buildings, highways, railways, large and medium span bridges, nuclear power plants and ground anchor projects. The utility model has the advantages of simple connection, simple anchoring, strong adhesive force, safe and reliable tension and tensioning, convenient construction, etc. the steel bar is saved, and the area and the weight of the component are reduced.
Q:Why is the price of screw steel affected by iron ore and coal?
The required material is simple, "billet, iron ore with a small amount of chemical elements", and then through the hot rolling method of refining, during which a large amount of coal is needed, so the price of rebar will be affected by iron ore and coal
Q:Why is thread steel thinner than crude?
Thread steel is used for the construction of reinforced concrete facilities, his material is generally low alloy steel grades is generally 16Mn (16 Mn low-alloy steel), or 45 carbon just, their yield strength is above 350Mpa, tensile strength 500Mpa, low carbon steel round steel than ordinary much higher (after heat treatment of the steel strength than low carbon steel nearly twice as high or higher)
Q:Why does the steel thread have longitudinal ribs?
The effect of the longitudinal ribs is indirect, which improves the mechanical properties of the transverse ribs and indirectly enhances the bond with the concrete.
Q:What are the specifications of thread steel?
Specification requirements for threaded steel shall be specified in the import and export trade contract.Generally should include the standard grade (type code), the nominal diameter of steel, nominal weight (quality), the length of the specifications and the allowable difference between the above indicators.
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
