GB/T 11354-2005
AbolishedDetermination of nitrided case depth and metallographic microstructure examination for steel iron parts
钢铁零件 渗氮层深度测定和金相组织检验
Application Summary AI generated
This standard specifies the methods for determining the depth of nitrided case layers and the procedures for metallographic microstructure examination of steel and iron parts. It is applied in the heat treatment and quality inspection of components such as gears, shafts, and molds that undergo nitriding processes to enhance surface hardness and wear resistance. The standard is primarily used in manufacturing industries, including automotive, aerospace, and heavy machinery, to ensure consistent case depth and proper microstructure for reliable performance.
