▪ Surface finished: NBK
▪ Dimension: OD4 mm - OD89 mm
. Wall Thickness: 0,5 mm - 15 mm 
. Tolerance: O.D (min) +/- 0.03mm, WT(min). +/- 0.03mm.
▪ High accuracy, excellent brightness, free of rust, no oxide layer, no cracks and other defects, high inside wall cleanness. And the high pressure carbon steel tubes are able to stand high pressure, No deformation after cold bending, no cracking after flaring and flattening. The complicated geometrical forming and machining can be realized. 
▪ Application: Precision tubes for hydraulic systems, automobiles, Diesel Engine, machinery, and other areas which require high precision, cleanness, and high mechanical properties performance.
