Nickel Alloy 625, Inconel^® 625

Alloy 625 is a popular nickel-chromium alloy that offers users a high level of strength and ease of fabrication. Also sold by Continental Steel as Inconel^® 625, alloy 625 is known for a number of different unique properties including:

• Strength due to the addition of molybdenum and niobium
• Outstanding thermal fatigue strength
• Resistance to oxidation and a wide range of corrosive elements
• Ease of joining through all types of welding
• Handles a wide range of temperatures from cryogenic to 1800°F (982°C)

Because of its versatility, a number of industries utilize alloy 625 including nuclear power production, marine/boating/undersea, and aerospace. Within these critical industries, you can find Nickel Alloy 625 and Inconel 625 in various applications including:

• Nuclear reactor cores and control-rod components
• Wire rope for cables and blades on Naval crafts such as gunboats and subs
• Oceanographic equipment
• Rings and tubing for environmental control systems
• Meets ASME code for Boiler and Pressure Vessels

In order to be considered alloy 625, an alloy must have a certain chemical composition which includes:

• Ni 58% min
• Cr 20-23%
• Fe 5% max
• Mo 8-10%
• Nb 3.15-4.15%
• Co 1% max
• Si .50 max
• P and S 0.15% max
