I've got a Polish steel with the make up.
Could you experts give a rough idea what to expect from this type of steel?

NC6

C-1.3-1.4% Mn-0.4-0.7 Si- 0.15-0.4 P max-0.03 S max 0.03 Cr 1.3-1.6 Ni max 0.35 Mo max 0.2 W max 0.2 V 0.1 Cu max 0.35
 
Is it hardened or annealed? I dont see anything that will make it really hard to polish. even in a hardend state, just start about 150-180 and go up through atleast 1200 grit. before hitting it on a sissal or felt wheel, and tripoli.
 
Ummmm...Jason....I don't think he wants to polish the steel. I believe he stated that the steel is Polish with a capital "P". You know. The country, Poland? ;) :D:D

I think our friend here wants some info on the characteristics and heat treatment of this steel. Neo, I've looked through some steel comp charts, but haven't found anything yet. Some of our more experienced memebers should be able to give you a good idea.

What you have looks alot like 52100, with traces of V. and W.......which
will probably prove to be a good thing.

Soak at 1500-1550f for at least 10 min. Quench into a fast oil to 100-125f,
and double temper at 350-400f/2 hrs ea.....as a starting point.

....should make excellent blades.
 
I'm not a knifemaker, just a user :o
I posted here because I thought this was the best place to ask knowledgeable people what to expect from this steel (from a user point of view)
I don't know about this steel NC6.
Only thing I know is that this steel is used for cuting tools,wood carving tools it is also used for mono steel knives by Polish knifemakers.
This steel can be heat treated to 62 hrc

This is what the knifemaker says:

Sorry for my poor English
57-59HRC
Concerned that the high carbon steel will be too fragile?
Perhaps if we can simple hardening on martenyzt and low tempering.
In these knives I use high and low temperature salt pot. Austenitizing in high temperatre salt and put to low temperature (~250C) salt a few hours.
"Austempering" procedure converted austenit to bainite. Bainite is very tough, give blade extra flexibility.

Yeah, I was leaning towards 52100 as well, but I don't know exactly what the traces of othe elements would do overall.

Could one create a bianite structure in 52100' ish steel?
I've only heard of bianite in relation with L6?
 
His austempering comments don't make much sense.
It's a higher carbon 52100. Nothing else to give you any other properties. So it's more wear resistant than 52100 but more brittle .Yes it would make good wood working tools !
 
I'm not an egg-spurt, but that is a very high carbon content and the amount of carbide formers don't look like enough to use it all, which might make it a borderline cast iron.

edit, Oh I wrote this but now I see Mete has chimed in.

Mete. Dumb question... is he going to need to do anything special to get all that extra carbon to from iron carbides rather than graphite?
