Deriving the Duplex name from the presence of both Austenite and Ferrite in similar proportions, Duplex Stainless Steels combine excellent corrosion resistance with high strength. The typical mechanical properties would be double that of a single phase austenitic grade such as 316, while, for example, offering superior stress corrosion cracking resistance in chloride solutions.

Standard Duplex Stainless Steels typically have a 22% Chromium and 5% Nickel and in the 1960's Langley Alloys developed the first 25% Chromium Duplex alloy, Ferralium 255, and coined the phrase Super Duplex.

Duplex Stainless Steel is at the heart of the Langley Alloys business, with Langley Alloys being the ONLY supplier today offering its customer the complete choice on Duplex, and Super Duplex grades, with stock in the following grades:

22Cr Duplex: UNS S31803 (F51) and UNS S32205 (F60) Alloy 2205.

25Cr Super Duplex grades: Alloy 255, UNS S32550 (F61), Alloy 2507, UNS S32750 (F53) Alloy 2507 and UNS S32760 (F55)

WNRF Flange, it is Weld Neck Raised Face (WNRF) Flange. The weld neck flange derives its name from the neck portion of the flange that is welded to the end of a piping system. Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. It is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange. Weld Neck flanges are costlier due to their design and engineering, and increased material.
