A283 steel coil exhibits excellent work hardening properties during cold forming for its high strength and plasticity. After repeated cold working deformation, the coil can still show similar strength and hardness, with even better ductility and toughness. In addition, due to its good welding performance, the coil can be easily welded into parts of various shapes and sizes, and the welding quality is stable and reliable. A283 steel coils are widely used in the manufacturing of various mechanical parts, such as bolts, nuts, pins and other standard parts as well as various non-standard mechanical parts. In addition, they are also used in the manufacture of building structural materials.

Carbon steel manufacturing process:
The smelting of carbon steel is usually carried out in converter and open hearth. Converters generally smelt ordinary carbon steel, while open furnaces smelt all kinds of high-quality steel. The technology of oxygen top blow converter is developing rapidly and it can replace open hearth furnace. The refined liquid steel is injected into the ingot mold to obtain various ingot. After the ingot is forged or rolled, it is processed into plates, strips, bars, and sections of various sectional shapes. Carbon steel is usually used directly in the hot rolled state. When used for manufacturing tools and various machine parts, it needs to be heat treated according to the requirements of use; As for steel castings, most of them are heat-treated.
Application
Application of carbon steel coil
1. Construction field:Carbon steel coil are often used in the manufacture of building structures, such as steel frames, steel beams, etc. Due to the high strength and plasticity of carbon steel plate, it can withstand large loads, so the widely used in construction.
2. Automobile manufacturing:carbon steel plate is an important material for manufacturing automobile body and frame. carbon steel tool It has good plasticity and welding performance, which can meet the requirements of automobile manufacturing.
3. Home appliance manufacturing:Carbon steel coil are often used in the manufacture of home appliances, such as refrigerators and washing machines.The carbon steel plate can be made into parts of different shapes through the stamping process to meet the needs of home appliances need.
4. Shipbuilding:Carbon steel plates are also widely used in shipbuilding. Due to the carbon steel tool Good plasticity and welding performance can meet the requirements of ship structure.
5. In other fields, carbon steel coil are also widely used in machinery manufacturing, petrochemical, metallurgy and other fields. area.
