Hard Chrome Plated Pipe Bar Introduction
Chrome plated Honed Tubes are presicion tubes with smooth inside and with chrome plated , they also could be skived and burnished pipe. Tubes or pipes inside tolerance could be H10, H9 or H8. Outside tolerance, wall thickness tolerance are produced according to seamless cold drawn tubes for precision application standard GB/T3639-2009 , EN10305 or DIN2391 standard. Material SAE1020, 20#, ST45, CK45, ST52, E355 tubes and so on for you to choose. IF you are looking for chrome plated tubes for hydraulic cylinder pipes or pneumatic cylinder tubes, please contact us without any hesitation.
