Abstract
A spectrographic solution technique utilizing either the porous cup or rotating disk electrode may be used to analyse high-alloy steels such as the corrosion and heat-resisting alloys, including the iron-chromium, iron-chromium-nickel, and iron-nickel-chromium groups Some types of low-alloy steel may also be analysed from the same analytical curves Cobalt is added as an internal standard, and iron, chromium, nickel, manganese, and molybdenum are determined with an accuracy in the order of ±2 to 3% of the amounts present. Interelement effects arising from wide variations in composition were indicated to be negligible. The procedure outlined is designed primarily for alloy identification or specification analysis, and is particularly useful where sample dimensions are not uniform
