Instant Steel Case Hardening: demonstration

[RoseMillCo]

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.

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.

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

[RoseMillCo]

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.

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

[kornfuelsme]

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.

[Frostman182]

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.

[RoseMillCo]

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.

How do you do this to get different colours?

thanks

[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.

[millimetreperfect]

Hi Good demo, are the fumes toxic and how expensive is it?

[melekrawlston]

how is the shock resistance of the steel? I have seen steel hat is hard like ceramic, but also chips like it as well.

[RoseMillCo]

correct....hard steels are brittle. but "case" hardening leaves the steel's original inner ductility unaffected while hardening the only the outer several thousandths (.010-.090).

when using cherry red, think of it as creating an "M&M" instead of a piece of hard candy.

[PV146]

The jump in hardness is pretty misleading. Let's assume you started with a low carbon steel, how about a 1040. It was probably annealed so its not extremely strong. Then when you case harden it, you quenched it which probably formed martensite. Since the piece was so thin it probably got through hardened. Not saying this doesn't work (it does), just don't expect a jump of over 30 RC

[RoseMillCo]

we have a customer that makes parts out of 1018 cr bars. starting RC is 28-30 & after treatment with Cherry Red they record RC 58-60. (using oven). Similar results reported w/flame hardening. our product infuses C into the outer several thousandths (.010-.090) while protecting the surface and allow the maximum amount of C to penetrate. you can get some hardening from heat & quench alone, but you simply cannot add carbon or harden deeper unless you use cherry red.

can u use that cherry red in a plasma spray coating?

[RoseMillCo]

don't know, but i suspect the plasma temperature would be too high, causing the powder to react before it ever hit the steel.

[Hegulator]

"Cherry red powder"

....ground up charcoal?

[RoseMillCo]

...not quite that simple. Cherry Red has a number of ingredients that make it effective on a number of different steels using different heating methods.

[travis112787]

is it safe to use on 4140 high carbon steel for guns parts

[RoseMillCo]

we have users working on 4130, 4140, and other chrome-moly steels with no issues.

[leloodallasmultipass]

yeah, great demo... I might get some stuff from youz.

[americafirst101]

ya great demo, Now spend some money and Buy an Induction Heating unit from me.

Have over 400 new and used........

[RoseMillCo]

thanks, but we don't do heat treating. we manufacture the product for use by heat-treaters, shop maintenance guys, etc....

[gunsnosyneighbor]

great demo...
