The cold process can remove the oxide layer outside to improve surface and offer better mechanical property, also can change ID,OD,WT to meet every client request.
3. Honed steel tube&SRB steel pipe
ID Tolerance: H8H9 or as client's request
ID Roughness: RA0.4micron(max)
Inner roughness: Ra0.2-0.8um
Straightness: 1:1000 or customized
This process can improve the roughness of the inner tube to 0.2-0.8um and make tube for cylinder using directly.
