• Plate up to 3” (76.2mm) in thickness

• Pipes in scheduled sizes, plus flanges and fittings to order

• Hollow bars

Super duplex stainless steels

Langley Alloys is the premier distributor of super duplex stainless steels. Having created the very first grade, Ferralium® 255, in the 1960’s we now stock the most complete range of grades. This is supported by our partnerships with blue-chip producers such as Alleima (Sandvik) and Voestalpine Bohler edelstahl. Our range of grades includes:

• Ferralium^® 255 (UNS S32550, DIN 1.4507, ASTM A182 F61) 

• S32760 (DIN 1.4501, ASTM A182 F55)

• S32750 (DIN 1.4410, ASTM A182 F53)

• S31803 / S32205 (DIN 1.4462, ASTM A182 F51/F60)

Nickel-based alloys

We continue to invest strongly in a range of popular nickel-based alloys that provide high-strength, a wide temperature operating range and resistance to stress corrosion cracking. These include:

• Alloy 718 (UNS N07718, DIN 2.4668)

• Alloy 625 (UNS N06625, DIN 2.4856)

• Alloy 725 (UNS N07725)

• Alloy 825 (UNS N08825, DIN 2.4858)

• Alloy 925 (UNS N09925)

• Alloy K-500 (UNS N05500, DIN 2.4375)

Several other grades in our portfolio reflect our rich history as a producer going back as far as 1938, including:

• the high strength Naval alloy Hiduron^® 130 (DIN 2.1504), which is now widely used in subsea components such as couplings, connectors, stab plates and valve trim.

• the copper bearing alloy Hidurel^® 5 (DIN 2.0855), used as a major engine bearing on the Spitfire aircraft and still specified in aerospace applications today.

With a number of metallurgists in our team, we are comfortable reviewing and meeting end user specifications – more than 2,000 of which are held in our system.

Added value services

Over the last few years, we have grown our ability to offer a range of added value services in-house with our own qualified inspectors and staff. This includes non-destructive testing such as ultrasonic and dye penetrant inspection; machining services including deep hole boring; additional product testing and 3.2 inspection.
