METALLURGICAL ENGINEERING EXPERT

ABOVE – IS A PHOTOMICROGRAPH OF STAINLESS STEEL THAT FAILED AS A RESULT OF INTERGRANULAR CORROSION – Intergranular corrosion is a selective attack in the vicinity of the grain boundaries of a stainless steel. It is as a result of chromium depletion, mainly due to the precipitation of chromium carbides in the grain boundaries. Chromium carbides can be precipitated if the stainless steel is sensitized in the temperature range 550–850°C (1020–1560°F), for example during heat treatment or welding.
