What is Inconel 625? – Composition & Characteristics
Inconel 625 is a nickel-chromium-molybdenum-niobium alloy designed to provide exceptional resistance to oxidation and corrosion across a wide range of temperatures. The high nickel content ensures resistance to chloride-ion stress cracking, while the addition of molybdenum and niobium enhances mechanical strength and creep resistance.
Key Properties of Inconel 625:
- Outstanding oxidation and corrosion resistance in harsh environments.
- Excellent mechanical strength even at elevated temperatures.
- Non-magnetic and easy to fabricate or weld.
- Superior resistance to pitting and crevice corrosion in seawater.
These properties make Inconel 625 ideal for industries where materials must perform reliably under high pressure, corrosive fluids, and extreme temperature conditions.
