    Abstract - (Show below) - (Hide below)

    Defines the method and apparatus for the measurement of the delta ferrite content, expressed as Ferrite Number (FN), in largely austenitic and duplex ferritic-austenitic stainless steel weld metal through the attractive force between a weld metal sample and a standard permanent magnet and the preparation and measurement of standard pads for manual metal arc covered electrodes.
