40cr steel pipe (40cr steel pipe) is a round steel with a hollow section and no joints around it. It is made of a solid tube blank through perforation to make a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. Compared with solid steel such as steel, when the bending and torsional strength is the same, the weight is lighter, and it is an economical section steel.

Application of 40Cr
After quenching and tempering, this steel is used to manufacture mechanical parts that are subjected to medium load and medium speed work, such as steering knuckles of automobiles, rear half shafts and gears, shafts, worms, spline shafts, top sleeves, etc. on machine tools; after quenching After quenching and tempering at medium temperature, it is used to manufacture parts that are subjected to high load, impact and medium speed work, such as gears, spindles, oil pump rotors, sliders, collars, etc.; Impact and wear-resistant parts, such as worms, spindles, shafts, collars, etc., with a solid thickness of less than 25mm on the section; Parts without great impact, such as gears, sleeves, shafts, main shafts, crankshafts, spindles, pins, connecting rods, screws, nuts, intake valves, etc. In addition, this steel is suitable for the manufacture of various transmission parts for carbonitriding, such as gears and shafts with large diameters and good low temperature toughness.
