Langley Alloys Duplex:: Langley Alloys Super Duplex UNS S32760:: Langley Alloys Super Duplex UNS S32750
In the 1960’s Langley Alloys developed the first commercially available 25% Chromium Duplex alloy, Ferralium 255, and coined the phrase Super Duplex. It pioneered the use of a deliberate nitrogen addition in order to improve ductility and corrosion resistance.
Super Duplexalloys are characterised by higher Chromium content than standard duplex stainless, typically around 25% and a PREN > 40 (PREN = Cr% + 3.3Mo% + 16N%) and offer improved corrosion resistance and better mechanical properties.
Langley Alloys offer all 3 grades of Super Duplex(Ferralium 255-SD50, UNS S32750 & UNS S32760) from stock in all forms

Ferralium 255 SD50sets a new bench mark for Super Duplex as the first to state 570N/mm2 as the minimum 0.2% Proof Stress. It offers excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, phosphoric and nitric acids.
In Seawater and other chloride containing environments Ferralium 255 SD50also provides outstanding resistance to pitting and crevice corrosion, with Critical Pitting Temperature exceeding 50°C.
Excellent ductility and impact strength at both ambient and sub-zero temperatures combine with a high resistance to abrasion, erosion and cavitation erosion.
Listed in NACE MR 01 75 for sour service and having gained ASME Approval for Pressure Vessel applications, Ferralium 255-SD50is tested to the highest degree using tests designed to guarantee that the trade-marked product possesses high integrity, a correct phase balance and the absence of sigma and other deleterious phases.
Ferralium 255 SD50is particularly applicable for large forgings, as the formation of sigma phase is much less likely than it is for other Super Duplexes.
