    High pressure boiler tube is a type of boiler tube that belongs to the category of seamless steel pipes. The manufacturing method is the same as seamless pipes, but there are strict requirements for the steel grade used in the manufacturing of steel pipes. High pressure boiler tubes are often subjected to high temperature and pressure conditions when used. Under the action of high-temperature flue gas and water vapor, the tubes can undergo oxidation and corrosion. Steel pipes are required to have high endurance strength, high oxidation and corrosion resistance, and good organizational stability. High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts, main steam pipes, etc. for high and ultra-high pressure boilers.

    Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation during cold bending, no expansion, flattening and no crack, it is mainly used to produce pneumatic or hydraulic components, such as air cylinder or oil cylinder, which can be seamless pipe or welded pipe.

    Compared with solid steel such as round steel, seamless steel pipe for structure has the same bending and torsion strength and lighter weight. It is a kind of economical section steel, which is widely used in the manufacture of structural parts and mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, construction steel scaffold, etc. It only requires strength and rigidity, but not tightness of steel pipe.

    40Cr steel is one of the most widely used steels in machinery manufacturing industry. After quenching and tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of the steel is good, and it can be quenched to the maximum when water quenched Ф 28 ~ 60mm, oil quenched to Ф 1540mmWhen the hardness is 174 ~ 229hb, the relative machinability is 60%. The steel is suitable for making medium plastic mould.
