The course presents key principles for selecting stainless steels and nickel-containing alloys for nitric acid service. It explains how nitric acid is produced, outlines the corrosion behaviour of various alloy families, and details how composition, microstructure, and operating conditions influence performance. The text also compares grades across a wide range of concentrations and temperatures, highlights challenges such as intergranular corrosion and stress-corrosion cracking, and offers guidance for choosing materials used in equipment throughout nitric acid plants.
