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 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 in 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
