analysis Inclusion Inspector

Non-metallic inclusions in steel are the cause for dangerous and serious material defects such as brittleness and a wide variety of crack formations. Non-metallic inclusions are sulfidic or oxidic in composition and are due to the melting process. All steels contain non-metallic inclusions to a greater or lesser extent. The type and appearance of these non-metallic inclusions depends on factors such as type of steel, melting process and the extent of shaping involved in getting the ingot or casting strand to a finished product. It is of particular significance to determine how pure the steel is. This provides information on the extent of sulfidic and oxidic non-metallic inclusions present.
