X1NiCrMoCuN25-20-7
1.4529Super austenitic 6Mo+Cu stainless — Alloy 926 / Incoloy 25-6MO. Enhanced version of 904L with higher Mo (6-7%) and N (0.15-0.25%). PREN 41-48 — rivaling super duplex but fully austenitic. Ni 24-26% eliminates stress corrosion cracking. Used for seawater systems, FGD, phosphoric acid production, offshore hydraulics, and salt extraction. Service -196 to +400°C.
