High Strength & Structural Integrity: Hot-rolled carbon steel coil offers superior tensile strength and durability, ideal for demanding industrial and construction applications. Cost-Effective Production: Manufactured through high-temperature rolling, it reduces energy consumption and production costs while maintaining consistent quality.
Steel coils are generally used in shipbuilding, automobile manufacturing, train manufacturing, rails, house steel bars, steel bridge manufacturing, steel pipe transportation 16Mn angle steel, oil, natural gas, widely used in engineering machinery and equipment, boiler container accessories, power equipment, mining equipment, machine tools, metallurgical equipment, coal mine machinery and equipment, shipbuilding, forging parts, power generation equipment and other fields
Hot rolled coils are rolled at high temperatures and have good ductility, toughness and wear resistance, which is beneficial for subsequent processing and application.
Cold rolling refers to a rolling method that changes the shape of steel by squeezing it with the pressure of rollers at room temperature. Although the steel plate will heat up during the process, it is still called cold rolling. Specifically, cold rolling uses hot-rolled steel coils as raw materials, and after pickling to remove the oxide scale, it is pressure-processed, and the finished product is hard-rolled coils.
Its tensile strength is as high as 355MPa, and its yield strength also reaches the corresponding standard, which makes Q355B steel plate have better strength and stability under large loads and complex working conditions. At the same time, Q355B steel plate also has good toughness and impact resistance, and can maintain stable performance in harsh environments.
Because they are produced by cold rolling process, the surface quality of these steel coils is good. For example, the surface of cold rolled coils is smooth and free of iron oxide scale, which can meet some application scenarios with high requirements on surface quality, such as ensuring the appearance of the coils when used in home appliance manufacturing.
