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.
