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)).
