ActiveIron, steel and alloy - Determination of nickel content - The dimethylglyoxime spectrophotometric method
钢铁及合金 镍含量的测定 丁二酮肟分光光度法
Application Summary AI generated
This standard specifies a spectrophotometric method using dimethylglyoxime to determine the nickel content in iron, steel, and alloys. It is applied in metallurgical laboratories and quality control settings for analyzing nickel concentrations in ferrous materials, particularly when high precision is required for alloy composition verification. The method is suitable for nickel content ranges typically between 0.01% and 2.0%, commonly used in the production and testing of stainless steels and alloy steels.
