ActiveMethods for chemical analysis of iron，steel and alloy--The potassium iodate titration method after combustion in the pipe furnace for the determination of sulfur content
钢铁及合金化学分析方法 管式炉内燃烧后碘酸钾滴定法测定硫含量
Application Summary AI generated
This standard specifies a method for determining sulfur content in iron, steel, and alloys by combusting the sample in a pipe furnace and titrating the evolved gases with potassium iodate. It is primarily applied in metallurgical laboratories and quality control settings for analyzing sulfur levels in ferrous materials, such as carbon steel, alloy steel, and cast iron. The method is used to ensure compliance with material specifications in manufacturing, construction, and engineering industries where sulfur content affects mechanical properties and corrosion resistance.
