Product Parameter
Product Show
Carbon steel coil is also known as low or high carbon steel plate and HRC coil, characterized by complete specifications,diverse materials; High dimensional accuracy, up to ± 0.1mm;Excellent surface quality, good brightness; Strong corrosion resistance, high tensile strength and fatigue strength; Stable chemical composition, pure steel, low inclusion content, widely used in construction, shipbuilding, vehicle manufacturing, machinery manufacturing, furniture and household appliances industry, electrical and automation industry.
A36 steel coil is mainly composed of iron, carbon, silicon, manganese, phosphorus, sulfur and other elements. Iron is the most dominant component, constituting more than 99% of the entire chemical composition. Its carbon content proportion is relatively high, around 0.2%, ensuring that the steel has a certain hardness and toughness. The addition of silicon, manganese and other elements enhances the strength and toughness of steel. The content of elements such as phosphorus and sulfur is low to ensure that the steel coil has good welding performance and corrosion resistance. A36 steel coil has excellent mechanical properties, and its tensile strength, yield strength, elongation and impact toughness are all higher than ordinary steel.
Product Features
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.
