The Elcometer 111-7F is a hand-held magnetic gauge for checking the delta ferrite content in stainless steel weld metal. It is pre-calibrated and simple to use. The readings are in Ferrite Number (FN) in accordance with WRC and IIW recommendations.
Operation
Place the nose of the gauge onto the weld metal and rest the middle of the gauge on adjacent parent metal. Turn the central wheel to the zero end of the scale, now turn it in the opposite direction until the magnet clicks off. Read the value.
What is Ferrite?
A minimum ferrite content in austenitic stainless steel weld metal prevents microfissures and hot cracks. Too much ferrite can lead to corrosion or embrittlement at high temperatures. It is a magnetic material in an essentially non-magnetic metal and so can be measured by the force of attraction due to a magnet.
