| ? ? ? ? 20Cr precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipes, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, the products mainly used to produce pneumatic or hydraulic components, such as air cylinder or oil cylinder, can be seamless pipe or welded pipe.
? ? ? ? The 20Cr precision steel pipe has high dimensional precision, smooth surface inside and outside, no oxide film on the inner and outer surface after heat treatment, no crack in the tube expanding and flattening, no deformation in cold bending, and can bear high pressure, and can make various complex deformation and mechanical deep processing treatment.
? ? ? ? Main steel pipe grades: 10, 20, 35, 45, 40Cr, 42CrMo, etc. through negotiation, precision seamless steel pipes of other grades can also be supplied. Main production bases: national standards of precision steel pipes in Shandong, Jiangsu, Chengdu, Tianjin, Hebei, etc; GB / t699-2008, national standard for precision steel pipe; GB / t3639-2008, in addition, GB / t8162-2008 structural precision steel pipe may also be used.
? ? ? 20Cr precision steel pipe is widely used in automobiles, motorcycles, electric vehicles, petrochemical, electric power, ships, aerospace, bearings, pneumatic components, seamless steel tubes for medium and low pressure boilers. It can also be used in steel sleeve, bearing, hydraulic, mechanical processing and other fields! The production process of precision steel pipe is the same as that of ordinary seamless pipe, which is the process of pickling and cold rolling after many passes.
