Part Number: ASTM94 or ASTM95 (all sizes) Relevant Use: Industrial use / Metal testing reagent . Manufacturer: Sturbridge Metallurgical Services Inc. 2017-11-07 Kalling’s No.2 Reagent (AKA Kalling’s etch, waterless Kalling’s) is a metallographic etchant for etching Ni-Cu, nickel-based superalloys, ferritic and martensitic 400 series stainless steels. This etchant will darken martensite, attack ferrite readily and etch austenite slightly. It will not attack carbides. Kalling’s 2g Copper Chloride 40ml HCl 40-80ml Ethanol: Useful etchant for superalloys and stainles steels as well as Ni-Cu alloys. Good for grain structure.

Click button to print your result.(For Desktop) Hastelloy C-276 is universally resistant to almost all corrosion. Sometimes, this may bring difficulties in etching marks on the alloy surface. Generally, 95 ml hydrochloric acid mixed with 5 gm. of oxalic acid are used as the etchant for Hastelloy C276.

A gel composition for use in etching the surfaces of teeth in preparation for prophylaxis, repair, or restoration, comprising an aqueous solution of an effective quantity of an acid; and a colloidal silica sol, wherein the silica portion of the sol comprises from about 3 to about 20 weight percent of the total etchant composition.

19 Waterless Kalling s 5gr CuCl cc HCl + Immersion or swab (ASTM E 407 designation is 95 Kalling s 2) Jun 11, 2018 Kalling's Reagent was chosen as the etchant because of its corrosive ability for nickel iron based superalloys such as IN718. This etchant This allows the composition to be varied (normally between 2 and 13 wt. that sample, an additional 5 seconds of exposure to the Kallings etchant was applied. Oct 13, 2020 Chemical composition of base metals was measured by optical emission polishing and two-step etching: chemical in Kalling's reagent (5 g Kalling's N.2 etchant was selected (5g CuCI2 + 100 mL HCI + 100 mL Methyl alcohol, using as input data the chemical composition of investigated Ni alloys.

Etching is a critically important process module, and every wafer undergoes many etching steps before it is complete. Etchant: Composition: Concentration: Conditions: Comments: Kalling’s No:1: Distilled water CuCl2: 33 ml: Immersion etching at 20° C: For etching martensitic stainless steels. Martensite will be dark and the ferrite will be coloured: HCl: 1,5 grams: Ethanol: 33 ml: Kalling’s No:2: CuCl2: 5 grams: Immersion etching at 20° C Although the selection of the best etchant, and its proper use, is a very critical phase of the image analysis process, only a few publications have addressed this problem. A classic example of the different behavior of etchants is given in Figure 20.2 where low-carbon sheet steel has been etched with the standard nital and picral etchants, and also a color tint etch. 1.
