Nickel 625 per AMS 5581
Nickel 625 (UNS N06625) as per AMS 5581 has a composition of a nickel, chromium, and molybdenum alloy, which is further strengthened with niobium, producing a tight crystal structure with high strength, not requiring any further heat treatment after the manufacturing process, and providing high resistance against any form of corrosion and pitting, thus being a good candidate even under harsh working conditions.
In a wide variety of industries: aircraft, chemical processing plants, marine engineering, oil and gas industries, nuclear reactors, and pollution control systems, to name a few, Nickel 625 combines high strengths with high corrosion resistance in hot and harsh environments.
- Chemical Processing – Reactors, heat exchangers, and piping handling corrosive chemicals.
- Aerospace – Jet engine components, exhaust systems, and high-performance structural elements.
- Marine Engineering – Propulsion systems, pumps, and valves exposed to seawater.
- Oil & Gas – Subsea equipment, risers, and offshore platform components.
- Pollution Control Equipment – Flue gas scrubbers, stacks, and treatment systems.
- Nuclear Reactors – Core support structures, heat exchangers, and cooling systems.
What is Inconel 625 ?
Nickel 625 (UNS N06625) is an austenitic nickel-base superalloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions, including jet engine environments and in many other aerospace and chemical process applications. Nickel 625 has outstanding strength and toughness at temperatures ranging from cryogenic temperature to 2000°F (1093°C). This alloy also has exceptional fatigue resistance. Nickel 625 derives its strength from the solid solution strengthening effects of molybdenum and columbium on the nickel-chromium matrix.
