Inconel – 600
INCONEL® 600 is combination of Nickel Chromium and Iron provides a standard material for the chemical industry and the automotive engine, aeroengine and airframe sectors. Controlled chemical composition limits are applied in the nuclear industry to eliminate the risk of stress corrosion cracking by high purity water containing chloride ions. From its introduction to industry in the 1930’s the alloy has developed into a wide spectrum of applications for high temperature strength and corrosion resistance. A widely used thermocouple sheath material in carbon or nitrogen rich atmospheres the alloy continues in use as an excellent muffle construction material and is also used for jigs and fixtures in heat treatment processes. Controlling the compositional limits and correctly processing and thermally annealing the material is essential to avoid pitting and the risk of stress corrosion cracking in some service environments.
With high nickel content, Inconel® Alloy 600 is virtually immune to chloride-induced stress corrosion cracking. The alloy has superb corrosion resistance to caustic environments. Inconel® Alloy 600 also demonstrates resistance to dry chlorine up to 538°C.
This alloy has excellent oxidation resistance up to 1093°C combined with high carburisation resistance. The alloy demonstrates good performance in high temperature nitriding environments.
It is not recommended that Inconel® Alloy 600 be used at red heat temperatures where sulphur is present. It has also been found that Inconel® Alloy 600 can fall victim to stress corrosion cracking in hot, concentrated caustic alkalis. However this can be avoided if the fabrication is fully stress relieved before use. Recommended stress relieving temperature of 982-1010 °C for 1 hour yields the best performance.
Alloy 600 can be used in a variety of applications, here are just a few examples:
- Heat treating muffles and retorts
- Vacuum furnace fixtures
- Nitriding furnaces and baskets
- Chlorination equipment to 538°C
- Titanium dioxide plants
- Chemical industry
- Heat treating industry
- Pulp and paper industry
- Food processing
- Nuclear Engineering
- Gas turbine components
- Alloy 600 is perfect for applications in Thermal Processing Industry
