Nickel-Chromium-Iron Alloys: JLC 600 series

JLC 600 is a nickel-chromium-iron alloy that provides superior resistance to oxidation at temperatures up to 1000 °C. It also provides good resistance against stress corrosion cracking in chloride environments. This alloy also offers good mechanical properties and workability. Owing to its good corrosion resistance properties at high temperatures, it is widely used in chemical and heat treatment industries. Since it maintains good mechanical properties at high temperatures, it is also used in the aeronautical industry to manufacture various aircraft and engine components.

JLC 601 is a nickel-chromium-iron alloy with a substantial chromium content that provides resistance to many corrosive media and high temperature environments. Oxidation resistance is further enhanced by addition of aluminum.
