Product Description

P530 Nonmagnetic Steel

 

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.
