SPHE: Made of low carbon steel and ordinary alloy steel pressed at high temperature SPHD: Thickness is 1.2~8mm. Strip steel with a width of less than 600mm is called narrow strip steel, and strip steel with a width of more than 600mm is called wide strip steel. SPHC: Add special elements (P, Cu, C, etc.), with good corrosion resistance and atmospheric corrosion resistance, used in the production of containers, special vehicles, and also used in building structures.
Hot rolled coils are rolled at high temperatures and have good ductility, toughness and wear resistance, which is beneficial for subsequent processing and application.
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.
The surface quality of hot rolled steel strip is one of its important characteristics. The standard specifies the allowable number and type of various surface defects to ensure that the surface quality of the strip meets the requirements, thereby reducing problems during processing and improving product quality.
Surface treatment: divided into three types of finishing surfaces according to precision: higher grade (FB), higher grade (FC), and super higher grade (FD) Derivative forms: In addition to steel strips/sheets, it can also be processed into bars, welded pipes, flanges and other structural parts International benchmarking: There is technical interoperability with the German DIN standard ST13 series
Specifically, these numbers represent the level of deep drawing performance. The larger the number, the better the deep drawing performance of the material. DC01 is a common material, not suitable for stretching, and only suitable for simple bending. DC02 can be used for shallow stretching, but is usually limited to bending. DC03 is called a stretching plate, and DC04 has the best stretching performance among the four materials and is suitable for deep drawing.
