Downhole hardware faces the most demanding combination in oil and gas: high pressure, high chloride, and sour service, at temperature, in one component.
We supply the age-hardenable nickel and super duplex bar that downhole tools are machined from, from stock in the UK and USA.
Which alloy for high-strength sour-service downhole components?
Alloy 718, Alloy 725 and Alloy 925 - age-hardening nickel alloys qualified for sour service under NACE MR0175 and ISO 15156 and API 6ACRA, for hangers, mandrels, landing nipples and setting components.
Which alloy for non-magnetic downhole tools (MWD/LWD)?
Fermonic® 50 - fully non-magnetic even after cold working, for drill collars and instrument housings where magnetic interference must be avoided.
Where does super duplex fit downhole?
Ferralium® 255 and the 25 percent chromium super duplex grades for corrosion-resistant, lower-strength parts.
Which alloy for high strength with marine corrosion resistance?
Alloy K-500, where nickel-copper strength and seawater corrosion resistance are needed together.
Also known as
Alloy 718, Alloy 725 and Alloy 925 are equivalent to UNS N07718, N07725 and N09925, sold elsewhere as Inconel® 718, Inconel 725 and Incoloy® 925, trademarks of Special Metals. Fermonic® 50 is our designation for UNS S20910, known elsewhere as Nitronic® 50, a trademark of Cleveland-Cliffs (formerly AK Steel). Ferralium® 255 is the Langley Alloys trade name for UNS S32550. Alloy K-500 is equivalent to UNS N05500, sold elsewhere as Monel® K-500, a trademark of Special Metals.
