Fry’s Reagent is a popular metallographic etchant for micro-etching precipitation hardening stainless steels (PH grade), martensitic stainless steels, and some superalloys. It is also an effective stain for weld inspection. When used in conjunction with the nital etch, it will stain the weld nugget and make it easier to see.

This product is made with ACS reagent grade cupric chloride, hydrochloric acid, ethanol, and water. This etchant is listed in ASTM standard E 407 as formula number 79 "Fry’s".
