Duplex Stainless Alloy 2205

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 31803 (F51) and UNS 32205 (F60)  Alloy 2205. 
25cr Super Duplex  grades:  UNS S32550 (F61), UNS S 32750 (F53) Alloy 2507 and UNS 32760 (F55)
