Metallographic Etchants (Micro Etchants)

Metallographic etchants are chemicals that can reveal microstructural details that would otherwise not be evident on a mirror-polished metal sample. The etchant will selectively etch or stain microstructural features, such as grain boundary or metal phases. These features can then be studied with a microscope.

Weld Inspection Etchants (Macro Etchants)

Weld inspection etchants are formulated by metallurgists to show weld features, such as nugget, heat affected zone, etc. These chemicals allow the user to inspect the weld and measure the penetration depth. They are effective, easy to use, and can be stored.
