ActiveMethods for chemical analysis of iron，steel and alloy--The combustion gravimetric/gas-volumetric method for the determination of non-combined carbon content
钢铁及合金化学分析方法 非化合碳含量的测定
Application Summary AI generated
This standard specifies the combustion gravimetric and gas-volumetric procedures for determining non-combined carbon content in iron, steel, and alloys. It is applied in metallurgical laboratories and quality control settings to analyze materials like cast iron, where free carbon (graphite) must be distinguished from combined carbon in carbides. The method is critical for evaluating material properties such as machinability and wear resistance in the production of ferrous alloys.
