ActiveSteel and iron -- Determination of nitrogen content -- Thermal conductimetric method after fusion in a current of inert gas (Routine method)
钢铁 氮含量的测定 惰性气体熔融热导法（常规方法）
Application Summary AI generated
This standard specifies a routine method for determining the nitrogen content in steel and iron by fusing the sample in a current of inert gas and measuring the released nitrogen using thermal conductivity detection. It is applied in metallurgical laboratories and quality control processes for the analysis of nitrogen in ferrous materials, such as carbon steels, alloy steels, and cast irons. The method is used to ensure material properties and compliance with technical specifications in steelmaking and metal product manufacturing.
