Chemical Composition

Mechanical Properties.

Delivery Condition

Cold finished (hard) BK(+C) Tubes do not undergo heat treatment following the final cold forming and, thus, have a

rather high resistance to deformation

Cold finished (Soft) BKW (+LC) The final heat treatment is followed by cold drawing involving limited deformation.

Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)

Cold finished and stress-relieved BKS(+SR) Heat treatment is applied following the last cold forming process.

Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming

and machining to a certain degree.

Annealed GBK(+A) The last Cold forming process is followed by annealing in a controlled atmosphere.

Normalized NBK(+N) The last cold forming process is followed by annealing above the upper transformation point

in a controlled atmosphere.

Surface:

1) NBK (Bright Annealed)

2) Galvanization/Galvanized/Zinc Coated

3) Blue White Zinc (Trivalent Chromium Passivation)

4) Plating Colour Zinc(Trivalent Chromium Passivation)

5) Yellow, Army-Green

6) Phosphated/Black Phosphated

7) Smooth outer and inner surface

Applications

1: for Car Fuel Oil

2: for Automotive Fuel Oil

3: for Injection Molding Machine

3: for Screw Air Compressor

4: For Excavator Hydraulic Pump System

5: for Air pneumatic Brake System
