Ferrite content analysis provides critical data pertaining to delta ferrite content in austenitic stainless steel and duplex materials. The delta ferrite percentage or number allows a technical assessment of material corrosion susceptibility, mechanical properties, service suitability and reliability.

Ferrite testing is performed on austenitic stainless steel and duplex items including (but not limited to) weldments, castings, weld overlays, wrought materials and forgings. Ferrite content analysis can be obtained on butt/fillet welds, stainless weld overlays on non-ferrous interfaces, cast components and pre- and post-weld heat-treated components.
