Close, but it is not ferrocyanide. Cherry Red contains 13 ingredients, each imparting certain properties to the hardening or the process. Ferrocyanide is not among the ingredients. As stated in other posts, it is not difficult to get at least some hardness by using a bunch of other methods. But Cherry Red was developed to easily get professional results case hardening a wide range of steels. It takes a lot of the thinking, trial and error, and guesswork out of the process.

might aswell as use and induction haeter, quicker and u cant burn urself ( well not from a flame any way)

First, Cherry Red is useful because it allows users to case harden steel parts without any special heat treating equipment, like an induction heater. Not many people have heat treating equipment.

Second, many of our customers use induction heaters while they are using Cherry Red. It is a quick, efficient way to heat the parts.

what kind of gas are you using?

[RoseMillCo]

gas? for the flame? it is a simple propane "plumber's" torch...to show that you can get good hardening results from commonly available items.

Although this process works, I would cryo treat material before I did this. Had much success with cryo treating material. Is it expensive, yes, but the results are excellent.

Cherry Red isn't intended to replace cryogenic hardening or other more sophisticated methods. Cherry Red allows users to effectively harden steel parts without relying in outside service companies or waiting for expensive methods.

"Cherry red powder"

....ground up charcoal?

[Mrpsychotehpyro]

No, its a Its a Ferrocyanide, at least most hobby use case hardeners are. The Industry would use Cyanide, which is a lethal poison. Ferricyanide is essentially non toxic and gets the job done too.

whats cherry powder? where could i get it or is there something else i could use?

[RoseMillCo]

the color stays pretty much the same if you know what you are doing. some of our users claim they can maintain near-original color.

our "demo" for this video wasn't very sophisticated, so the colors you see may be from a lack of controlling the lighting or simply incomplete coverage of the part.
