P540 Nonmagnetic Steel

1. CHEMICAL COMPOSITION

P540 is a special nonmagnetic, austenitic Mn-Cr-N-steel with a nitrogen content of ≤ 2%.

C Mn Cr Mo N Ni
max. 0,05 19,00 – 21,00 17,00 – 19,50 0,30 – 0,80 min. 0,50 0,80 – 2,00

2. MECHANICAL PROPERTIES

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

TEXT OD KSI N/MM
Yield Strength (min.) 0,2%-offset method: OD up to 9 1/4“ 120 ksi 830 N/mm²
OD 9 1/2“ and larger 110 ksi 760 N/mm²
Tensile Strength (min.): 130 ksi 900 N/mm²
Elongation (min.): 0.2 0.2
Reduction of area (min.): 0.5 0.5
Impact energy (min.): 90 ft.lb 122 J
Endurance Strength / N=10⁵ (min.): ± 65 ksi ± 455 N/mm²
Hardness Brinell: (min.): 285-400 HB 285-400 HB

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, Pract.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 using a Förster 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.

We are committed to integrate steel resources in china and serve the global steel market. Our company has more than 15 years of experience in steel researching, production, managing and sales.
