AMS 5869 / Alloy 625 Sheet – Factory Price | ISO 9001 & AS 9120B Certified Manufacturer & Supplier
Product Overview
AMS 5869 specification covers a corrosion- and heat-resistant nickel alloy in the form of sheet, strip, and plate up to 1.000 inch (25.40 mm) in nominal thickness.
Alloy 625, also known as NiCr22Mo9Nb or UNS N06625, is a nickel-based superalloy with a wide operating temperature range – from cryogenic to highly elevated temperatures – making it ideal for use in aerospace engines and gas turbines. It displays superb corrosion resistance and is available in Grade 1 (annealed) and Grade 2 (solution annealed).
ZYTC Alloy is an ISO 9001 and AS 9120B certified superalloy manufacturer and supplier, offering AMS 5869 Alloy 625 sheet at factory-direct prices with full material traceability and fast global delivery.
Key Features – Alloy 625 Sheet (AMS 5869)
✅ Wide operating temperature range – Cryogenic to highly elevated (aerospace engines & gas turbines)
✅ Superb corrosion resistance – Outstanding performance in aggressive environments
✅ No precipitation hardening required – Stiffened by molybdenum and niobium on nickel-chrome matrix
✅ Resilience to oxidation & carburization – Excellent high-temperature performance
✅ Excellent SCC & SSC resistance – Stress-corrosion cracking & sulfide-stress-cracking resistant
✅ Excellent for seawater applications – Salts do not easily cause localized pitting
✅ Available in Grade 1 (annealed) & Grade 2 (solution annealed)
✅ NACE MR0103 compliant – Softer heat charge with hardness < 35 HRC for petrochemical applications
✅ Good weldability – Solid all-round material grade
Strength of this alloy is derived from the stiffening effect of molybdenum and niobium (columbium) on the nickel-chrome matrix – therefore a precipitation hardening treatment is not required.

Why Alloy 625 for Seawater Applications?
Alloy 625 is an excellent choice for seawater applications because:
Salts do not easily cause localized pitting
High resistance to chloride-induced corrosion
Excellent performance in constant salt exposure
Numerous marine applications are manufactured from 2.4856 (Werkstoff equivalent) for this reason
