MATERIAL DESCRIPTION, MAIN CHARACTERISTICS

The alloy 625 is a low-carbon nickel-chromium-molybdenum alloy with a niobium addition, excellent resistance to pitting, crevice corrosion and stress-corrosion. It has an excellent resistance to corrosion-fatigue and erosio-corrosion.
Highly resistant in a wide range of organic and mineral acids, it has a good resistance to high temperature corrosion in some oxidizing sulfur/chloride media. Good properties at temperatures up to 450°C (840°F).
