What is Inconel 625?
Inconel 625 is a nickel-chromium-molybdenum alloy renowned for its exceptional corrosion resistance, strength, and toughness. The alloy contains niobium and molybdenum, which enhance its resistance to pitting, crevice corrosion, and high-temperature oxidation.
Because of these properties, Inconel 625 performs efficiently across temperatures ranging from cryogenic levels up to 982°C (1800°F). This versatility makes it ideal for both onshore and offshore environments.
