Q:Excuse me, Shagang steel steel, what is the sign of
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. 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 two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade
Q:What is the difference between the II and III grades of threaded steel?
Third grade rebar than ordinary II rebar strength increased about 20%, is designed for building construction of reinforced structure is developed, the yield strength of 400Mpa (grade HRB400), is the country to promote the use of excellent products.
Q:Are thread steels of coarse steel?
Thread steel does not belong to coarse steel, rough is shaped steel, fine is wire.
Q:What is the specific concept of thread steel through water and what is the difference?
The principle of water cooling technology to produce rebar is that austenite can be strongly deformed in the process of continuous rolling in the recrystallization zone, resulting in very fine, strongly hardened austenite grains with a lot of defects. With the high speed of cooling on the enhanced cooling of austenite, in a very short period of time, generally not more than 0.5s, is rapidly cooled to near the phase transition temperature, inhibit the growth of austenite grain, try to keep the hardening state of austenite. When the temperature is near the phase transition point, the fine hardening austenite grains are transformed into ferrite with proper grain size under proper air cooling conditions.
Q:Why is round bar more expensive than thread steel?
Steel is divided by tolerance standard of gb. You say there is no comparable price between round bar and screw thread. You can't use round bar as thread steel or thread as round bar!
Q:Why is the difference between left and right threads? What's the difference?
The design direction of rotation screw steel, steel and related crystal. Due to crystal dislocation, under the tensile stresses along a surface slip between the crystal, for single crystal, slip surface and tensile stress direction angle of about 45, at the same time, the crystal will around the stress-induced rotation axis. According to the characteristics of steel, the surface of the reinforcement design into a spiral shape, can effectively improve the strength of steel, save materials, reduce the weight of the building. Of course, there are combined with concrete between considerations.
Q:Why do stirrups have thread stirrups and round bars? When are they used?
Your question is actually related to steel and concrete work of a force of synergy in the reinforced concrete structure, steel usually is in tension, in order to ensure the reinforcement force can be well transferred to concrete, so as not to slip, we put the steel processing into whorl ribbed or other rib the shape, its purpose is to increase the adhesion between steel and concrete. Round steel is usually used in lower grade, smaller diameter reinforced steel, mainly because of its low strength, without adding ribs, round bar and concrete bonding between the relay can ensure that its strength is very good play. Therefore, steel bars are mainly used in places where the force is not large and the calculation of the reinforcement is very small.
Q:What are the main uses of threaded steel?
The main use of rebar is to use beams and columns of important structures as well as bridges. The upper rib is stronger than the round steel when combined with concrete pouring!
Q:What's the difference between primary and two grade steel and three grade steel?
There are two kinds of commonly used classification methods of thread steel: one is to shape classification, according to different space shapes and transverse rib rib for classification or type, such as the British Standard (BS4449), the thread steel is divided into type I and type ii. This classification mainly reflects the tightening performance of the threaded steel.
Q:Why the longitudinal tie bar adopts screw steel bar, and the transverse transmission bar adopts light round steel bar.
Steel is known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand. 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 two levels, HRB335 (old No. 20MnSi), three HRB400 (20MnSiV, 20MnSiNb, old No. 20Mnti), four grade HRB500 three grade.
