Alloy 600
Introduction :
Alloy 600 is a nickel-chromium-iron, solid solution strengthened alloy used for applications that require corrosion and elevated temperature resistance. Service temperatures for alloy 600 can be from cryogenic to 2000°F. This alloy also has good workability, weldability and high strength.
Overview
The addition of chromium provides superior corrosion resistance in acidic environments, compared to a pure nickel, while allowing the material to maintain corrosion resistance in a reducing state and exhibit superior corrosion resistance to alkaline solutions. Nickel Alloy 600 can be used in solutions of magnesium chloride because of its exceptional resistance to chloride stress corrosion cracking. It has exceptional strength at working temperatures up to 2000ºF (1093˚C).
Applications
• Nuclear power plants.
• Heat exchangers.
• Industrial chemical evaporators.
• Industrial acid and alkali equipments.
• Heat treatment furnace parts.
• Afterburner parts and other components used at high temperatures.
• Vacuum furnace fixtures.
