The high size precision, good surface quality, superior performance, is a kind of high quality welding steel wire rod.

Main uses: mainly used for carbon steel hot rolled strip steel core discmanufacturing welded with the medicine skin.

9 structural alloy steel hot rolled wire coil (GB3077-82), alloy structure steelhot rolled wire rods by alloy structure steel as material and rolling. Alloystructural steel has a total of 26 Steel Group, 78 steel grades. Each productionplant according to any requirements and different use of selected grades for production.

Main uses: mainly used for structural alloy hot rolled wire drawing steel wire,metal products and structures.

10 carbon tool steel hot rolled wire coil (GB1298-86), carbon tool steel by high quality or high quality high carbon steel and rolling. The processing performance and wear-resisting performance is good, the price is cheap.

Main uses: mainly used for drawing steel ratio and manufacturing tools etc..

11 alloy tool steel hot rolled wire rod (GB1299-77)

Alloy tool steel is in the matrix of the carbon tool steel adding chromium,tungsten, molybdenum, vanadium, silicon, manganese, nickel and cobalt alloyelements and tempered steel. Compared with the carbon tool steel. It has good hardenability and cracking tendency of small, wear resistance and high heat resistance characteristics of heat treatment. Alloy tool steel, alloy tool steel hot rolled wire rod is composed of 5 steel group of 33 steel as the material and rolling. Are produced by the unit of the Dalian steel plant, Benxi steel andShaanxi steel etc..

Main purpose: is used for making the measuring tools, tools and cold and hot working die, shock resistant tool etc..

12 hot rolled spring steel wire rod

Spring steel is used in steel manufacturing springs or elastic element. The spring and the elastic element is mainly the use of the elastic deformationenergy absorption and storage, to mitigate the vibration and impact of theparts or do some action for the purpose of. Because it is periodic alternating inshock, vibration or long-term uniform stress conditions, so the requirements of spring steel has a high yield strength, especially to a higher ratio of yield strength (yield strength and tensile strength ratio) and high temperature resistance and corrosion resistance。

Q:What is a steel wire rod?
The delivery of long wood is divided into two pieces: fixed gauge and coilYou refer to the wire rod, refers to the coil delivery of steel, under normal circumstances, according to commonly used, refers to the coil delivery of round steel, also known as smooth steel,
Q:Can decarburization occur in low carbon and low alloy wire rods? Why?
According to the truth, because of containing carbon steel, oxidation must occur in the heating process, and alloy steel, some alloy increases the decarburization tendency of carbon steel, low carbon steel so will produce decarburization, especially in high temperature and long time stay in the process.
Q:Types of wire rods
There are many kinds of wire rods. Carbon steel wire rod in the low carbon steel wire rod, commonly known as cord, medium and high carbon steel wire rod commonly known as hard wire. Wire rods are mainly used for drawing billets, and can be used directly as building materials and machined into mechanical parts. Stainless steel wire rod is used for making stainless steel wire, stainless steel spring steel wire, stainless steel wire and stainless steel wire rope. With the development of production technology, square has appeared,
Q:What is a wire rod?
Wire rods, also known as wire rods, steel, wire, rod (s), usually refer to small diameter round steel discs. The diameter of the wire rod is in the range of 5-19 millimeters (usually 6-9 mm), and its lower limit is the minimum size of the hot-rolled steel section.
Q:What is the difference between a wire rod and a straight bar?
Wire rod refers to the delivery of goods in the form of plate delivery, usually with a finer steel, diameter less than 12. When used to straighten, has the advantages of convenient transportation, storage, basically no waste material
Q:What are the common diameters of steel bars?
Round bar is in fact the ordinary low carbon steel small round and round. Deformed steel bars are ribbed steel bars, usually with 2 longitudinal ribs and transverse ribs uniformly distributed along the length. The transverse rib shape is helical, herringbone, crescent 3. Expressed in millimeters of nominal diameter. The nominal diameter of deformed steel bar is equal to the nominal diameter of the round steel bar of equal cross section. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm. Steel grades: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bond ability of concrete, deformed steel bar can bear the effect of external force better. Reinforcement is widely used in various building structures. Especially large, heavy, light, thin-walled and high-rise structures.
Q:If the surface shrinkage of wire rod is poor, what will happen to wire drawing?
If the surface shrinkage of the wire rod is poor, the drawing process will break, because the surface shrinkage is the shrinkage of the cross section, and is the plastic index of the wire rod. Because of the low reduction rate of drawing, it is often less likely to occur because of shrinkage during drawing.
Q:8 wire rods, one meter, how many kilograms?
Round steel rod (kg/m) W= 0.006165 * D * d d = diameter mm, diameter 100 mm round steel, for every m weight. Weight per M = 0.006165 * 1002=61.65kg
Q:Round in high wire and ordinary line what is the difference?
P line: refers to the use of "ordinary mill (usually open-train double wire rod rolling mill)". The rolling speed of 20-60 meters per second, per root weight (disc) in 0.4-0.6 tons (market show is generally three root six head is a market), in the rolling process can only be cooled by air cooling or air cooling line to ensure product performance.Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.
Q:What is a cold drawn steel wire? What does it usually do?
A low carbon steel wire that is worked out to produce cold working hardening.
