Q235 Steel Pipe is carbon structural steel used to transport low pressure fluids. This type of steel is generally smelted by converter or open hearth, and its main raw material is molten iron plus steel. The content of sulfur and phosphorus in steel is higher than that of High-Quality Carbon Structural Steel, generally sulfur ≤ 0.050%, phosphorus ≤ 0.045%. The content of other alloying elements brought into the steel by the raw materials, such as chromium, nickel and copper, generally does not exceed 0.30%. Q255A, B, Q275 and other steel grades are indicated.
The carbon structural steel Q235 in the GB700-88 standard is divided into four grades A, B, C and D according to the metallurgical quality. The Si content of each grade is 0.3%, and the difference lies in the carbon content, sulfur and phosphorus content. different. The carbon content of AB grade is 0.14%~0.22% and 0.12%~0.20%, the carbon content of CD grade is ≦0.18%, ≦0.17%, the Mn content of A grade is the smallest, and the SP content of D grade is the smallest.
Q235 steel pipe is used to transport low pressure fluid. Generally welded pipes are made of Q195A, Q215A, Q235A steel. Can also be made from other mild steels that are easy to weld. The steel pipe needs to be tested for water pressure, bending, flattening, etc., and has certain requirements on the surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver to a fixed length (or multiple feet). The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe can be divided into two types: ordinary steel pipe and thickened steel pipe according to the specified wall thickness.
Q235 steel pipe can be used for various abrasive handles and other unimportant abrasive parts. Q235 steel is used as the punch material. After quenching, it is used directly without tempering. The hardness is 36~40HRC, which solves the phenomenon that the punch is broken during use.
