Factors Affecting Inconel 625 Price
• High Nickel Content: Over 58% nickel makes the alloy highly sensitive to global nickel price fluctuations.
• Alloying Elements: Molybdenum, chromium, and niobium add strength and corrosion resistance but increase material costs.
• Manufacturing Process: Cold working, seamless rolling, and surface treatments impact the final price.
• Certification & Origin: Mill certifications (EN10204 3.1/3.2) and country of origin (USA, EU, China) affect export prices.
• Order Quantity: Bulk orders usually get better rates due to economies of scale.
Applications of Inconel 625
• Aerospace: Jet engine exhaust systems, thrust-reversers, bellows
• Marine: Offshore platforms, heat exchangers, seawater piping
• Chemical Processing: Reactor vessels, tubing, pressure vessels
• Power Generation: Heat recovery systems, steam lines, turbines
• Nuclear: Waste management systems, reactor cores
