Corrosion Resistance ASTM B444 N06625 Inconel Seamless U Bend Tube
What is Inconel 625?
Inconel 625 is a corrosion and oxidation resistant nickel alloy used for its high strength and excellent resistance to aqueous corrosion. Its excellent strength and toughness are due to the addition of niobium, which, together with molybdenum, hardens the matrix of the alloy.
Alloy 625 has excellent fatigue strength and resistance to stress corrosion cracking from chloride ions. This alloy resists a wide range of severely corrosive environments and is particularly resistant to pitting and crevice corrosion.
Corrosion Resistance of Inconel
Inconel 625 has corrosion resistance to many environments. In mild environments such as atmosphere, fresh water and sea water, neutral salts and alkaline media there is almost no attack. In more aggressive media nickel and chromium resist oxidising attack, while nickel and molybdenum resist reducing environments.
Molybdenum provides exceptional resistance to pitting and crevice corrosion, and niobium stabilises against sensitisation and intergranular corrosion. The nickel content makes Inconel 625 essentially free from chloride ion stress corrosion cracking. Inconel 625 also has excellent corrosion fatigue properties.
UNS N06625 products are furnished in two grades of different heat-treated conditions:
1.1.1.1 Grade 1 (annealed)—Material is normally employed in service temperatures up to 1100°F (593°C).
1.1.1.2 Grade 2 (solution annealed)—Material is normally employed in service temperatures above 1100°F (593°C) when resistance to creep and rupture is required.
