Cold Rolled Ordinary Thin Steel Plate

Cold rolled ordinary thin steel plate is a kind of steel plate that is made of cold rolled steel plate, which is processed by processing hot-rolled steel plate. The thickness of the cold-rolled steel plate is generally below 4mm and the thickness of the hot-rolled steel plate is over 4mm. Cold rolling is usually used to make thin steel plates with complex shapes and improved strength and excellent surface quality.

Cold rolled ordinary thin steel plate has high strength, good plasticity and toughness, good heat treatment performance and weldability. It has excellent process performance, low forming force and good drawing performance. The cold-rolled thin steel plate has good corrosion resistance and can be machined with better surface finish. The cold-rolled steel plate can be used for various applications, such as automotive parts, industrial parts and other parts.

Cold rolled ordinary thin steel plate is widely used in the manufacture of thin tanks and enclosures that require increased strength, such as pressure vessels and other structural applications. Cold rolling and hot rolling technology can be customized according to customers’ needs, and the steel plate can be provided with different surface treatments, such as galvanizing, painting, oiling and other surface treatments.

Cold rolled ordinary thin steel plate is generally divided into several grades, such as SPCC, SS400, DC01, etc. According to the applicable standard, the production process is determined by the different requirements of the product functions, such as high degree of plasticity, uniform yield strength, good surface quality, and internal and external weldability. The cold-rolled thin steel plate is characterized by thin thickness and good surface quality.

The cold-rolled thin steel plate is usually adjusted by cold-rolling, but during the process, the cold-rolled thin strip is required to maintain a certain degree of mechanical properties and surface quality, so the corresponding heat treatment is required after cold rolling. Common heat treatment processes include annealing, normalizing, quenching and tempering.

Cold rolled ordinary thin steel plate is widely used in automotive parts, industrial parts, electrical appliances and other fields. The cold rolled steel plate can be cut into various sizes according to the customers needs, and various complex shapes can be formed by laser cutting and punching. The cold-rolled thin steel plate has high strength and excellent surface finish, so it can meet the needs of customers for complex shapes, thin thickness and high precision.

Cold rolling ordinary thin steel sheet

Cold rolling is a process of forming sheet metal by passing it through a pair of rolls. Cold rolling is widely used to produce ordinary thin steel sheets. Cold rolling technology has the advantages of high production efficiency, good quality, low cost and high precision.

Ordinary thin steel sheet is a kind of metal material which is widely used in the production of parts and components in machinery and equipment, such as building and construction industry. Compared with other metal materials, ordinary thin steel sheet has the characteristics of high strength, good toughness, good plasticity and welding performance, strong corrosion resistance and so on. At the same time, it is easy to process and has a uniform thickness. Ordinary thin steel sheet is suitable for cutting, lathing, drilling, welding,electroplating and other processes, which can meet the requirements of various industries.

Cold rolling is divided into cold-reducing and cold-hardening. Cold-reducing is suitable for cold rolling ordinary thin steel sheets. The cold-rolled steel is heated to its recrystallization temperature before cold rolling. After cold rolling, due to the continuous plastic deformation of the metal, the grains of the metal are broken and their theoretical size becomes smaller. This greatly improves the properties of the metal, and improved strength, hardness and plasticity, and also improves the surface quality.

Cold rolling is an important cold work forming method, which can produce high precision products with high physical and mechanical properties. It is widely used in the production of ordinary thin steel sheets, and it can meet the requirements of various industries.
