PVQ A516 grade 70 boiler steel plate,The seamless steel pipe for general use is rolled by common carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.

PVQ A516 grade 70 boiler steel plate,In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. It has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
