A method is described of determining, with an estimated probable error of ±½, the percentage of ferrite in a stainless steel weld by measurement of the saturation intensity of magnetization of the weld. A calibration curve for 18/8/1 stainless steel is given, and is correlated with curves obtained with iron in wax specimens. There seems no reason why the range of 2 to 18% ferrite content actually measured should not be extended, using modified apparatus.
