Steels and cast irons; Determination of molybdenum content; Photometric method

This technical specification outlines a photometric method for determining the molybdenum content in steel and cast iron. The procedure involves dissolving the sample and converting molybdenum into a stable colored complex suitable for quantitative analysis using visible light spectrometry. It provides detailed instructions on reagent preparation, calibration standards, and measurement parameters to ensure accurate results. The methodology is designed to handle typical concentrations found in these ferrous alloys, addressing potential interferences from other elements commonly present in the matrix. By establishing consistent analytical steps, this document facilitates uniform testing practices across laboratories. It serves as a reference for quality control and material certification processes within the metallurgical industry. The approach emphasizes precision and reproducibility, allowing for reliable comparison of data obtained under different conditions. Implementation of these guidelines helps maintain high standards in the chemical analysis of iron and steel products.
