Product Description

1. CHEMICAL COMPOSITION

P530 is a special nonmagnetic, austenitic Mn-Cr-N-steel with a Nickel-content of ≤ 2%.

C	Mn	Cr	Mo	N	Ni
max. 0,05	18,50 - 20,00	13,00 - 14,00	0,40 - 0,60	0,25 - 0,40	max. 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 less than 4"	120 ksi	830 N/mm²
	OD 4" to 91/4"	110 ksi	760 N/mm²
	OD 91/2" and larger	100 ksi	690 N/mm²
Tensile Strength	OD less than 4"	130 ksi	900 N/mm²
	OD 4" and larger	120 ksi	830 N/mm²
Elongation (min.):		0.25	0.25
Reduction of area (min.):		0.5	0.5
Impact energy (min.):		90 ft.lb	122 J
Hardness Brinell: (min.):		260-350 HB	260-350 HB

 

3.MAGNETIC PROPERTIES:

Relative permeability: ≤ 1,001.

 

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.

 

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.

 

6. GALLING RESISTANCE

P530 is due to the chemical composition and the special cold working process less susceptible to galling than Cr-Ni steels.

 

The Non-magnetic drill collar is made of a kind of low carbon high chrome-manganese alloy steel, material normally is P530 or P550 or higher grades, which is refined after strict chemical composition ratio and forged to achieve its mechanical properties, this kind of drill collar has superb mechanical properties of low permeability and high strength. Mainly used for down hole directional drilling.
