According to its shape of section, we could classify wire rod as a sort of steel, and actually it is an exclusive variety of steel. The hot rolled round steel bar with diameter from 5 to 9mm and reinforced steel less than 10mm of its diameter are generally defined as wire rod. Wire rod generally is produced with coil-temper mill, therefore, it is also named coil rod.
Wire rod is one of the most required steel materials, which are provided market with. The wire rod processed by crimped could be used in the fields of construction or welded structure and also could be applied after deep process. For instance, after being drawn, it could be produced into wires of different specs. We can make rope through twist them together. Besides, we could weave net and manufacture springs. It is available to be produced into rivets, bolt, machine parts, and steel etc.
Wire rod is made from common carbon steel and high quality carbon steel. We could sort the wire rod in the respect of the catalogues and usages: Ordinary low-carbon steel hot-rolled rods, High-quality carbon steel wire rod, Quenched and threaded rod, steel wire rope, piano wire rod and stainless steel wire rod and so on.
1. Ordinary low-carbon steel hot-rolled rods(GB701-65)
Ordinary low-carbon steel hot-rolled carbon rods are made from ordinary carbon structural steel or carbon structural steel rolling with a lower yield point. This rod is of the largest amount wire varieties and the most widely used rod, so it is called common wire.
Main usages: mainly used in the construction of reinforced concrete structures for reinforcement use, can also be made of cold drawn steel wire as binding wire.
2. Ordinary low-carbon steel non-twist and controlled cooling (or hot) rolled wire rod (ZBH4403-88)
it is made through being processed by no twisting high-speed wire rod mill. The material is identical with common wire; however, there are more aptitudes: High dimensional accuracy, Surface quality, higher mechanical properties.
Main usage: No twist and controlled cooling, hot-rolled rod size precision points A, B, C 3. A, B, C-level precision for drawing, construction, packaging and welding purposes, B, C-level precision for processed into bolts, screws and nuts and so on.
Main usage: the size precision of No twist and controlled cooling or hot-rolled rod sorts as: A level, B d level and C level. A, B, C-level precision for drawing, construction, packaging and welding purposes B, C-level precision for processed into bolts, screws and nuts, etc.
3. High-quality carbon steel wire rod (GB4354-84)
High-quality carbon steel wire rod is made of quality carbon structural steel rolling. This is the amount of wire species, one of the larger species.
Main usage: high-quality carbon steel wire rod is mainly used for manufacturing carbon spring steel wire, oil tempered carbon spring steel wire, priestesses steel wire, high-strength high-quality carbon steel wire, galvanized steel wire, galvanized wire rope, etc.
4. High-quality carbon steel non-twist and controlled cooling, hot-rolled wire rod (ZBH44002-88)
High-quality carbon steel non-twist and controlled cooling, hot-rolled wire rod are made from the non-high-speed wire twisting </ B> made rolling mill, rolling taken after the controlled cooling treatment. Compared with high-quality carbon steel wire rod, it is of a high dimensional accuracy, surface quality, and higher mechanical properties.
Main Usage: The main purpose with the same high-quality carbon steel wire rod. Commonly used in the manufacture of carbon spring steel wire, oil tempered carbon spring steel wire, priestesses steel wire, high-quality carbon structural steel wire, galvanized wire and so on.
5. Steel wire rope with wire rod (YB349-64)
Steel wire rope with wire rod is one of High-quality carbon structural steel hot-rolled rods
Main usages: it is made from 35, 40, 45, 55, 60, 65, 70, 75, 80, and 85# steel. The chemical materials comply with GB699.
6. Steel wire rope torsion-free and controlled cooling, hot-rolled wire rod (ZBH44004-88)
This variety of steel wire with high dimensional accuracy, surface quality, superior mechanical properties.
Main usage: used to produce drawn steel wire and strand wire rope.
7. Carbon electrodes steel wire rod (GB3429-82)
Carbon electrodes steel wire rod is made from low carbon structure steel by being crimped.
Main usages: Manual metal arc welding core.
8, carbon steel non-twist control rod cooling, hot-rolled wire rod (ZBH44005-88)
Carbon steel non-twist control rod cooling, hot-rolled wire rod is made by twisted wire mill rolling blockade and carry out controlled cooling after rolling is made. Its high dimensional accuracy, surface quality, superior performance, is a high-quality welding steel wire rod.
Main use: Mainly used to produce a drug skin welding steel hot-rolled carbon steel core rods.
9, Piano Wire Rod (GB4355-84)
Piano Wire Rod is made from 60, 60 Mn, 65, 65 Mn, 70, 70 Mn, 75, 75 Mn, 80, T8MnA, T9A high-quality carbon structural steel by being crimped.
Main usages: piano wire rod is mainly used for drawn with piano wire, oil quenching and tempering steel valves and so on.
10, carbon tool steel Hot-rolled coil (GB1298-86)
Carbon tool steel is made from high-quality or high-quality high-carbon steel rolling. Processing
Performance and wear resistance is good, cheap.
Main usage: Mainly used to drawn steel and manufacture of steel tools.
