Description of material
GL5 is a Nickel – Iron – Chromium – Aluminum alloy with high resistance in several corrosive media in high temperature environments.
Applications
This grade has been designed to warrant high performance in applications requiring high resistance to high temperatures in oxidation, carburizing and carbo-nitriding environments. The structure and composition of GL5 offers an excellent resistance to several corrosive aggressive media from cryogenic up to high temperature environments. GL5 is suitable for the fabrication of many products such as installations in industrial furnaces working in different atmospheres, in petro-chemical processes, in the automotive industry in high temperature devices/sensors, heat exchangers, heating elements, furnaces and muffles, chains, burners, evaporators, incinerators and in applications involved high temperature oxidizing environments.
