Inclusion
Rating/Raw Material Cleanliness: Metal's contain non metallic elements and
compounds causing reduction in strength and many other issues including
effecting the metals response to heat treatment. These non metallics refered to
as inclusions are in some cases aid the
component in enhancing its machinability. However, in most cases these non
metallics reduce the engineering property of the metal and contaminate the metal
with non desirable constituents. We are able to prepare the specimens per
standards and conduct cleanliness rating or
dirt count and rate the material with a simple table. In steels the inclusions
are 4 main groups listed as silicates, aluminas, sulfides, and oxides.
