AbolishedMethods for chemical analysis of ferroniobium--The EDTA volumetric method for the determination of aluminium content
铌铁化学分析方法 EDTA容量法测定铝量
Application Summary AI generated
This standard specifies the EDTA volumetric method for determining the aluminium content in ferroniobium, an alloy used in steelmaking and superalloys. It is applied in metallurgical laboratories and quality control processes to ensure the correct aluminium composition in ferroniobium, which affects the alloy's deoxidation and grain refinement properties. The method is critical for verifying material specifications in the production of high-strength low-alloy steels and heat-resistant alloys.
