Product Description Product Description P650 HS Nonmagnetic Steel1. CHEMICAL COMPOSITIONP650 is a special nonmagnetic, austenitic Mn-Cr-Mo-N-steel with a high pitting corrosion resistance, specifically developed for oilfield applications.CMnCrMoNNimax. 0,0619,50 - 20,5018,00 - 19,001,70 - 2,000,55 - 0,653,00 - 4,502. MECHANICAL PROPERTIESFollowing mechanical properties (tested at room temperature) are achieved by a special cold-working process over the full length of the collar:TEXTODKSIN/MMYield Strength (min.) 0,2%-offset method:OD up to 9 1/4"140 ksi965 N/mm2 OD 9 1/2" and larger130 ksi900 N/mm2Tensile Strength (min.): 150 ksi1035 N/mm2Elongation (min.): 20%20%Reduction of area (min.): 50%50%Impact energy (min.): 60 ft.lb82 JEndurance Strength / N=10 5 (min.): 60 ksi414 N/mm2Hardness Brinell: (min.): 330-430 HB330-430 HB3. MAGNETIC PROPERTIESRelative permeability: ≤ 1,005.4. CORROSION RESISTANCETransgranular 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, Pract.A and E, last edition.Pitting Corrosion: Due to a high chromium-, molybdenum- and nitrogen contents a high resistance to pitting corrosion is given.5. NON-DESTRUCTIVE TESTINGMagnetic 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.Detailed PhotosCompany ProfileEquipment and ProcessApplicationPackaging
