AbolishedMethods for chemical analysis of iron，steel and alloy--The sodium fluoride separation--EDTA titration method for the determination of aluminium content
钢铁及合金化学分析方法 氟化钠分离-EDTA滴定法测定铝含量
Application Summary AI generated
This standard specifies the sodium fluoride separation-EDTA titration method for determining the aluminum content in iron, steel, and alloys. It is applied in metallurgical laboratories and quality control settings for chemical analysis of ferrous materials, particularly when precise measurement of aluminum is required for material certification or process monitoring. The method is suitable for analyzing samples where aluminum is present as an alloying element or residual component.
