AbolishedStandard test methods for rating and classifying inclusions in steel―Scanning Electron Microscope
钢中非金属夹杂物的评定和统计 扫描电镜法
Application Summary AI generated
This standard specifies the test methods for rating and classifying non-metallic inclusions in steel using a scanning electron microscope (SEM). It is applied in the metallurgical industry for quality control and material characterization, particularly for high-performance steels used in automotive, aerospace, and bearing applications where inclusion size, composition, and distribution must be precisely evaluated. The standard provides a quantitative alternative to traditional optical microscopy, enabling automated statistical analysis of inclusions for improved product reliability.
