MA601

Ni-23Cr-14Fe-1.35Al (mass%)
Nickel chrome alloy featuring outstanding aspects both in corrosion resistance and heat resistance

Main Features

MA601 is resistant to high temperature oxidizing atmosphere up to 1205°C, and has excellent carburizing resistance. The oxidation resistance is mainly achieved by chrome, and the relatively high aluminum content of this alloy further improves the oxidation resistance.Mainly used for heating furnace, heat treatment furnace, thermocouple protective tube, glow plug, gasoline engine thermal reactor, petrochemical industry heater, etc.

Weldability/Workability

Molding process and welding can be easily performed.Use INCO-WELD A, INCONEL WELDING ELECTRODE182 for arc welding. Use INCONEL FILER METAL 82, INCONEL FILER METAL 601 for TIG.
