There are two kinds of thread classification methods:First, the geometric shapes are classified and classified according to the cross sectional shape of the ribs and the pitch of the ribs. For example, the British Standard (BS4449), the steel is classified into type I and type ii.Two is in the performance classification (grade), for example our country standard (G B1499), according to the strength level (yield / tensile strength) will be divided into 3 grades of thread steel;s
If the steel is a tiger, so is the wing steel containing vanadium vanadium, like the tiger wings. Only a few percent of vanadium in the steel, can make the elastic strength of steel, increase abrasion resistance and spalling resistance excellent, high temperature resistance and resistance in the car, no wonder the bitterly cold, aviation, railway, electronics, defense industry and other departments, can be seen everywhere traces of vanadium. In addition, vanadium oxide has become one of the best catalysts in the chemical industry, called vanadium, the "chemical bread". Mainly used in the manufacture of high speed cutting steel and other alloy steels and catalysts. The vanadium doped vanadium steel can be made into steel. A more compact structure than ordinary steel vanadium steel, toughness, elasticity and higher mechanical strength. Preparation of vanadium steel penetrators, can penetrate 40 cm thick steel plate. However, in the iron and steel industry, is not the pure metal vanadium steel to make vanadium steel, the vanadium ore smelting vanadium steel.s
Finishing rolling rebar diameter of JL32-- 32mm, 32 - screw steel hot rolled ribbed steel bars, the difference between the two: 1, ribbed bar is injected directly into the concrete, increase of steel concrete.s
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.s
