ActiveChromium metal - Determination of aluminium content - EDTA titrimetric method and flame atomic absorption spectrometric method
金属铬 铝含量的测定 乙二胺四乙酸二钠滴定法和火焰原子吸收光谱法
Application Summary AI generated
This standard specifies two methods for determining the aluminium content in chromium metal: the EDTA titrimetric method and the flame atomic absorption spectrometric method. It is applied in the metallurgical industry for quality control and chemical analysis of chromium metal used in the production of stainless steel, superalloys, and other high-performance alloys. The standard ensures accurate measurement of aluminium, which can affect the mechanical properties and corrosion resistance of the final alloy products.
