The measurement of delta ferrite in austenitic stainless steel welds is commonly done in the shop with magnetic instruments. One problem with this indirect approach is that the magnetic measuring device will respond not only to delta ferrite but to all magnetic influences. This study describes the observed effects of rapid cooling from the liquid phase, room temperature distortion (cold working) and heat-treatment on the measurement of ferrite in types 308L, 309L, 316L and 347 stainless steel weld metal. A comparison is drawn between the measured values and those calculated from the chemical analysis, and reasons for the difference are suggested.
