Inconel 625 (UNS N06625) is the most versatile and widely used nickel alloy — combining outstanding corrosion resistance across a wide range of environments with excellent fatigue strength and high-temperature capability up to 980°C. The niobium addition strengthens the alloy by solid-solution and precipitation hardening. The go-to choice when standard stainless steel grades have failed.
