Conditions Kalling’s No. 1 Distilled water CuCl 2 Hydrochloric acid Ethanol 33 mL 1.5 g 33 mL 33 mL Immersion etching at 20 ºC Kalling’s No. 2 CuCl 2 Hydrochloric acid Ethanol 5 g 100 mL 100 mL Immersion etching at 20 ºC Kellers Etch Distilled water Nitric acid This product is made with ACS reagent grade cupric chloride, hydrochloric acid, and ethanol. The formula is listed in ASTM standard E 407 as formula number 94 “Kalling’s 2”. Some people call this solution waterless Kalling’s . Superalloy Etch is a modified, stronger version of Kalling’s no. 2 reagent.

The optimal time varies for each cell line. Volumetric Karl Fischer reagents come with a variety of options. Composites (5,2,1) working with solvents is most popular but if you're looking for longer stability you may want to consider Titrants + Solvents.

Therefore, it is easy to etch the layered structure in 310S-WM after PWHTs using relatively weak acid (Kalling’s reagent). In contrast, the phase interface (δ L /γ) in the as-welded state was necessarily etched by strong acid of aqua-regia, indicating similar composition between δ L and γ-phase in the layered structure ( Fig. 5 (b)).
