JLC 800 offers corrosion resistance, heat resistance, and strength under high temperature conditions up to 600 °C. It is also resistant to stress corrosion cracking, oxidation, carburization, and sulfidation at high temperatures. It is readily formable, weldable, and machinable. The alloy maintains a stable austenitic structure during prolonged exposure to high temperatures.
JLC 810 is similar to JLC 800, but with a slightly higher carbon content and an optimized grain size. The higher carbon helps with better creep and stress rupture properties. This alloy is prefered over JLC 800 when service temperatures range between 600-800 °C.
JLC 825 is a nickel-chromium-iron alloy with molybdenum, copper, and titanium additions. It offers excellent resistance to general and localized corrosion in many different environments. It is resistant against pitting, crevice corrosion, chloride-ion stress corrosion cracking, and reducing environments containing aggressive sulfuric and phosphoric acids.
