Useful etchant for superalloys and stainless steels as well as Ni-Cu alloys. Good for grain structure. Generally used a swab etch.
Flammable Liquids, Corrosive, n.o.s. (Ethanol, Hydrochloric Acid, Cupric Chloride mixture), 3(8), UN2924, PG II
Ferrite and Martensite are darkened. Austenite appears light and carbides are unaffected. For Stainless Steels.
