carbon steel powder

[Bob]

From where can I buy small quantities of powdered carbon steel in the uk?

Hi Bob

to the Surface Engineering Forum.

I think we need more information to be helpful. Chemical composition, purity, particle size/shape etc.. If you are not sure then tell us the function/application for the powder.

Hi Gordon,

I'm looking for a medium carbon steel (say 0.6 - 0.9 %carbon) in powder form. I've tried shot blasting grit but it's a wee bit too course. The application is nothing to do with metal spraying, I'm trying to make my own powder crucible steel!

[Gordon]

Hi Bob

Have you thought of trying the fine swarf from filing or turning?

[Bob]

They're too course and often too oily! What we are trying to do is this:

We take an old chainsaw or motorbike chain and coil it in a can. We then add powder and vibrate the can so that the powder fills the gaps in the chain. Next we heat to just below the melting and allow to soak. The final step is placing the can in a hydraulic forging press to fuse the metals together. The results can be seen here:

Hi Bob

I see what you are trying to do now, very artistic. You are after a fine free flowing powder that packs well.

I tried a quick search, but really only ended up finding this message thread

I think you need to contact a few powder metallurgy supply companies, but I suspect you will have problems with minimum order quantities. Thermal spray powders would probably work and usually supplied in smaller quantity, but your choice in carbon steels will be limited and price may be high. Maybe you could also consider using high chromium steel or alloy tool steel powders.

Sorry not very helpful, hopefully someone will come along with a useful lead.

Hi everybody,

I, myself am looking for a similar thing (med to high carbon, plain (or low alloy) steel in powder form) for a very similar reason (though strictly speaking this is not crucible steel, it's instead a method for making what we call damascus steel (welded in a canister rather than melted in a crucible))

Bob, if you would like to send me an email, I can point you in the direction of some overseas suppliers, or possibly join me (& probably a few others from the forum I normally frequent) in a "group buy" to save some pennies (it's almost always cheaper to buy in larger quantities)


Sorry to interrupt, back to you guys


Thanks

Not sure, but try to talk with Hoganas, Sweden

Hi Bob.

Has the material got to be carbon steel or would a cast iron powder do?

Also have you a size range in mind?

I ight be able to help if the material used can be cast iron.

Regards.

Pete

Try to talk with Sandvik, Sweden, they are the specialistds in Carbon steel powders.

Hi.

What size range is the material required as I might have a UK source for carbon steel powder.

Apologies for tagging on to this thread but i couldnt see how to start a new topic and this thread is vaguely related!
We are looking to form a ferritic layer (carbon or mild steel or cast iron) to 20mm aluminium (to allow it to be heated by induction) and apply a hard surface (such as keronite) to the other side of the aluminium. Is this possible with plasma spraying? and who might be a good company to contact?
Thanks in advance

[djewell]

Any kind of thermal spray should be able to apply the ferritic layer onto aluminum as you described. The questions you need to answer are what level of porosity and oxidation can you tolerate and how much bond strength do you require. Also, could you use a stainless steel layer instead of carbon steel?

I could use 430 stainless steel, would that maintain its stainless ness after the flame spraying?

[djewell]

Yes, it will maintain its properties. You may need to seal it to prevent corrosive gases or liquids from penetrating to attack the aluminum substrate.

thanks for the info :-)

Hi Bob,


Help yourself
1. Fill a large container with water.
2. Load an electric arc equipment with sprasteel 80 wire.
3. Spray the wire in water for several minutes.
4. Remove the powder from the water recipient and dry it.
5. If you want a certain grain, you have to pass it through a sieve.
Good luck!
