P530HS Non Magnetic Drill Collar

One of the main strengths of ShunFu is the ability to be a single source manufacturer of special Non Magnetic collars. Only those products which successfully pass our rigorous inspection controls are allowed to leave our factory. From the sourcing of materials to the final quality control all ShunFu manufactured products pass through our precision machining production steps including BTA boring, CNC lathe and milling, roller burnishing, shot peening, long distance gunhole-drilling and laser cladding at a 6-axis machine.

The reputation of ShunFu in the manufacture and supply of Non Magnetic drill string components is based upon extensive in-house experience both in metallurgy and precision manufacturing. ShunFu has always been the leader in the development of Non Magnetic materials, special manufacturing processes and testing procedures such as hammer peening and hot-spot testing.

Being specifically focused on the manufacturing of nonmagnetic drill string components makes ShunFu a leader in complex precision machining and service at the highest of standards.

Drill Collars are made from high purity
austenitic stainless steel.

Low & High Yield Material available

Advanced chemical composition control system and special forging process guarantee the excellent mechanical properties, corrosion
resistant performance and high fatigue resistance of our Non- Magnetic material.

Shoot Peening on Connections.

Chemical Composition

P530HS is a high pitting corrosion resistant nonmagnetic, austenitic Mn-Cr-N-steel, specifically developed for oilfield applications.

Element P530
P530 HS
Carbon max. 0.05
Manganese 18.50-20.00
Chromium 13.00-14.00
Molyddenum 0.40-0.60
Nitrogen 0.25-0.40
Nickel max. 1.50

Mechanical Properties

Following mechanical properties (tested at room temperature) are achieved by a special cold-working process over the full length of the collar:

Yield Strength (min.): OD up to 9 1/2″ 120 ksi 830 N/mm2
0,2%-offset method    OD 9 1/2″ and larger 110 ksi 760 N/mm2
Tensile Strength      (min.): 130 ksi 900 N/mm2
Elongation        (min.): 25% 25%
Reduction of area  (min.): 50% 50%
Impact energy     (min.): 90 ft.lb 122 J
Hardness Brinell: 285-365 HB 285-365 HB

Magnetic Properties

Relative permeability: < 1,001

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, Pract. A and E, last edition.

Non-Destructive testing

Magnetic inspection: Drill collars are 100% tested by a proprietary probe-testing process using a Forster Magnetomat 1.782. (“Hot Spot”-test). 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.

Galling Resistance

“P530HS” is due to the chemical composition and the special coldworking process less susceptible to galling than Cr-Ni steels.

P530HS Non-Mag Drill Collars meet all requirements of API Spec. 7.1, last edition. All tests are carried out according to ASTM-Standards, last editions.
