Description

Characteristics

• Resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy **0 and **1 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.
• Virtually immune to chlorine ion stress corrosion cracking.
• Demonstrates adequate resistance to organic acids such as acetic, formic and stearic.
• Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors.
• Little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to **0C in these media, this alloy has been shown to be one of the most resistant of the common alloys.
• At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength.
• The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.
• Under alternating oxidizing and reducing conditions the alloy may suffer from selective oxidation
