Does anyone happen to have any information on this steel or if this is even an actual type of steel or some kind of proprietary reference to a type of steel. The reason I ask is I have a few pieces of broken saw blades for a very, very large hydraulic reciprocating saw and that is the only reference number I could come up with. The steel is extremely hard as it will wreaks files with gusto.
 
I did a little bit of research, and it turns out that it is a HSS. http://www.codesol.com/fotos/fichas/13.pdf

The biggest thing you are going to run into is heat treatment. There is a very small possibility that you will actually be able to heat treat it correctly, and an otherwise good knife with a bad heat treatment is worthless. Even if you send it to a pro, they have to know what to do with it when it gets there.

Thanks for the info. I had managed to dig up the same little bit of info on the saws as yourself but I guess what I am trying to ask is what exactly is hss is 98-37-414 and if anyone has any more detailed information on it.



I do know that when it breaks it has a very fine and consistent structure throughout.

Years ago I rough shaped a few blades with the intention of sending to someone to have them re-tempered to a proper knife hardness.

If anyone knows anything on the physical properties of this particular steel I would really love to know a little more.
 
It is my assumption that it is a brand name or designation. If you are dead set on using it, I would suggest sending some off for analysis. However, it would probably be cheaper to just buy steel.

I hope someone else is able to help you.
 
Just use it as it is. "Proper" knife hardness goes from 53 to 65 HRc
 
if it is a HSS it is most likely going to be close to other hss steels when it comes to heat treat test a few small peices try heating to 2000 degrees and plate quench see if that gives you a very brittle steel if it does that is a good start then on the other peices of steel do different tempers testing on all of the the brittleness until you get the results you want

i would start at high heat of 2000 degrees with a 20 min soak time first stopping at 1400 degrees for 10 mins

then temper at 600 degrees going up or down in temperature for your liking most likely up from 600 degrees test it and tell us your results :) i would love to here it.

The steel is still in its original form as partial pieces of the saw blade and I don't have any of the tools necessary to test the steel at my current location. If you would be interested in doing some testing yourself I might be able to part with a piece or two. Send me a PM.
