Non-metallic inclusions are chemical compounds and nonmetals that are present in steel and other alloys. They are the product of chemical reactions, physical effects, and contamination that occurs during the melting and pouring process. These inclusions are categorized by origin as either endogenous or exogenous.
Non-metallic inclusions consist of chemical compounds and nonmetals present within steel and similar materials. They arise from chemical interactions, physical processes, and contamination during the manufacturing phase. These inclusions can be categorized into two types: those originating internally (endogenous) and those introduced externally (exogenous).
