Metallographic Etchants (Micro Etchants)
Metallographic etchants are chemicals that can reveal microstructural details that would otherwise not be evident on an as-polished sample. The etchant will selectively corrode microstructural features, such as grains or grain boundaries. These features can then be studied with a microscope.
Weld Inspection Etchants (Macro Etchants)
Weld inspection etchants are formulated by metallurgists to show weld nugget, heat affected zone, penetration depth, etc. These macro etching chemicals are very effective for visual inspection of welds.
