HB 5220.16-2008 Methods for chemical analysis of superalloys. Part 16: Determination of vanadium content by ammonium ferrous sulfate volumetric method (English Version)
This part specifies the principles, reagents, instruments, sample preparation, analysis steps, calculation of analysis results, tolerances, and quality control and requirements for the determination of vanadium content in high-temperature alloys using the ferrous ammonium sulfate volumetric method. This section applies to the determination of vanadium content in high-temperature alloys. This section does not apply to the determination of vanadium in samples containing more than 20% cobalt and more than 0.01% cerium. Measuring range: 0.20% ~ 5.00%.
