3. MAGNETIC PROPERTIES

Relative permeability: ≤ 1,005.

4. CORROSION RESISTANCE

  • Transgranular SCC: Prevented by special surface treatments (Hammer peening, roller burnishing, shot peening).
  • Intergranular SCC: The occurrence of material sensitization is prevented by quenching after warmforging. Each collar is tested according to ASTM A 262, Prat.A and E, last edition.
  • Pitting Corrosion:Due to a high chromium- and nitrogen content a high resistance to pitting corrosion is given.

 

5. NON-DESTRUCTIVE TESTING

  • Magnetic inspection: Drill collars are 100% tested by a proprietary probe-testing process. Magnetic permeability of each collar is certified with the printout of probe-testing.
  • Ultrasonic inspection:Each collar is ultrasonically inspected over 100% of the volume according to ASTM E 114, last edition as a minimum level.

6. We can also offer other kinds of material:P550 P530 P580, P650, P750, P750
