ISO 4967 Non-Metallic Inclusion Rating in Steel
The ISO 4967 standard provides a method for rating non-metallic inclusions present in steel. This service is essential for quality assurance, product development, and compliance with international standards. The process involves detailed examination of the microstructure to identify and classify the types of inclusions and their impact on material performance.
The examination typically begins with careful preparation of a polished cross-section or surface sample from the steel specimen. This is followed by etching, which enhances the visibility of the non-metallic inclusions for easier identification under a microscope. The评级：
