ActiveFerroniobium - Determination of sulfur content - Combustion-iodate titrimetric method，methylene blue photometric method and infrared absorption method
铌铁 硫含量的测定 燃烧碘量法、次甲基蓝光度法和红外线吸收法
Application Summary AI generated
This standard specifies three methods for determining sulfur content in ferroniobium: combustion-iodate titrimetry, methylene blue photometry, and infrared absorption. It is applied in the metallurgical industry for quality control and acceptance testing of ferroniobium, an alloy used in steelmaking and superalloy production. The standard ensures accurate sulfur measurement, which is critical for controlling material properties and preventing brittleness in final products.
