Promoted ignition and more recently promoted combustion are terms which have been used to describe a situation where a substance with low oxygen compatibility ignites and supports the combustion of a more combustion resistant material. Previous work has been reported on the investigation of this phenomenon as it relates to carbon steel, stainless steels and a number of significant engineering alloys in the nickel, cobalt and copper families.

Alloys which were tested in this investigation included: AL-6XN stainless steel, 347 stainless steel, INCO A weld filler metal, HAYNES HR-160, HAYNES 214, HAYNES 230, HAYNES 556 and HAYNES ULTIMET.

These alloys represent a substantial range of alloy composition, capability and cost. Potential service environments include hazardous waste, marine, heavy industrial, electronics and various elevated temperature applications where oxygen enriched environments may be encountered.
