Ardrox 1435 is a two part alkaline liquid concentrate containing an oxidizing material. It is primarily intended as an aid in removing difficult heat scale such as those produced on high chromium steels and nickel and cobalt alloys, which are notoriously difficult to remove even with strong acids. Ardrox 1435 will not normally remove such scales by itself, but will chemically and physically modify them in such a manner as to make them more easily removable by milder and less dangerous methods than the use of strong acids.
The main field of use for Ardrox 1435 is the overhaul of “hot end” components of gas turbine engines. Ardrox 1435 has also been found useful for the removal of adherent carbon smut produced after heat treatment.
