Application Summary AI generated
This standard specifies three methods—molybdenum blue photometric, silicon potassium fluoride titrimetric, and perchloric acid dehydration gravimetric—for determining silicon content in ferromanganese, ferromanganese-silicon, nitrogen-bearing ferromanganese, and manganese metal. It is applied in the metallurgical industry for quality control and chemical analysis of these manganese-based alloys and metals, particularly during production, inspection, and acceptance testing.
