GB/T 24583.2-2009 specifies an inert gas melting thermal conductivity method for the determination of nitrogen content in vanadium-nitrogen alloys. The standard details the sample preparation steps to ensure that the samples are representative. Clear requirements are put forward for test equipment, such as inert gas melting devices, Thermal Conductivity Meters, etc., including equipment accuracy, Stability, etc. During operation, key parameters such as flow rate, melting temperature and time of inert gas are strictly regulated. By following this standard, the nitrogen content of vanadium-nitrogen alloys can be accurately determined, providing key data support for alloy production, quality control and application in steel and other industries, and helping enterprises to improve product mass and production efficiency.
