Precision Carbon Steel Tube for Oil Hydraulic Tube (OST-2) (OST-II TUBE)

 

Feature OST-II TUBE

1. High quality and quick delivery
   We deliver high quality 'Precise carbon steel tube for Hydraulic tube' by a short delivery date with a consistent quality assurance flow from manufacturing to inspection.
2. Nondestructive test
   We will never overlook injurious defects by nondestructive test (eddy current inspection) for all materials.
3. Bright heat treatment
   Inner and Outer surface of the tube become scaleless because we use bright annealing furnace for final heat treatment.
