45# precision
steel pipe has high precision and smoothness, no oxide layer on inner and outer wall, can withstand high pressure, no deformation of cold bend, flaring, flattening without crack, etc. The round pipe of 45# precision steel pipe is mainly used to produce pneumatic or hydraulic components. Products such as automotive steel pipes, oil drill pipes, etc. Shaped steel tubes in precision seamless steel tubes are widely used in various structural parts, tools and mechanical parts. The difference between precision steel pipe and seamless steel pipe is that it has high dimensional accuracy and can reach 0.05mm.
The principle of 45# precision steel pipe pickling means that the tube blank of 45# precision steel pipe has a clean and active surface to ensure the surface quality of the precision steel pipe produced. In order to obtain such a surface, the scale of the scale is removed (except when annealing under a protective atmosphere or a reducing atmosphere).
45#The inner and outer walls of precision steel pipe have no oxide layer, withstand high pressure and no leakage, high precision, high smoothness, no deformation of cold bending, flaring and flattening without cracks; often used in hydraulic system piping, automobile manufacturing piping, military engineering, engineering machinery, Railway locomotives, aerospace, ships, injection molding machines, die casting machines, machine tools, diesel engines, petrochemicals, power stations, boiler equipment, and other industries.
