Fry’s Reagent, 500 mL



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 the weld easier to see. This product is made with ACS reagent grade chemicals and it’s listed in ASTM standard E 407 as formula number 79 “Fry’s”. We have a stronger version of Fry’s called Macro Fry’s, which is designed for forensic studies.
