Precision Steel is a kind of high-precision cold drawn or hot rolled steel material after processing by. Because precision steel inside and outside the wall oxide layer, to withstand high pressure without leakage, high-precision, high-quality finish, cold deformation, flaring, flattening without cracks, etc., so the main pneumatic or hydraulic components used to produce precision steel products, such as 45crmo precision steel cylinder or cylinders, which can be seamless Shandong precision steel tubes, welded pipe there. National standard national standard precision steel; GB / T699-2008 35 precision steel tubes, the national standard precision steel; GB / T3639-2008, in addition may also apply GB / T8162-2008 structural precision steel tubes. Precision steel European standard is: DIN2391 basic purpose of precision steel tubes are widely used in automobiles, motorcycles, electric cars, petrochemical, power, ship, aerospace, bearings, pneumatic components, the low-pressure boiler seamless steel tubes and other areas, is also applicable to steel sleeve cylinder, bearings, hydraulic, mechanical processing and other fields!
