sorry i may be asking in the wrong spot but has anyone worked with eiher steels if so what would you compare them too and thank you
 
Murray Carter is the only American that I know of that has extensive experience with those two steels. You might try to contact him through his website.
 
Shirogami ( white steel) - 1.30C, .30 Mn, .25 Si, .05P
Aogami (Blue Steel) - 1.15C, .50Cr, .30Mn, .25Si, 1.5W

White steel is similar to some formulations of W-1
O-7 is similar to Blue steel

Does anybody know of a suppier for the blue or white steel?

Thanks

good luck

last time I checked, Hitachi wanted $7/lb plus shipping with a 1000lb minimum, thats for White#2
I asked a member of the Tokyo knife guild about super blue...he laughed and said that even he couldn't get it.
 
I found some white and blue #2 on a German site but it came out to like 200$ with shipping for like 3 feet of it
 
Talk to Murray Carter about getting some. I know that he travels to Japan to source it and get a shipping container sent, along with other specialized Japanese supplies that he uses (charcoal, quenching mud, etc).
 
just save yourself the hastle and use W1...

I've used white #2, and have 2 pieces still. The biggest thing I've found is that hitachi is very consistant in their yss steels, (unlike some of steel you can get in the US that varies as to the ammounts of alloying elements ) it makes them very consistant in heat treating.

You can get white and blue to really high hardness. I'm sure you know that already though.

That's here in Germany. They specialice in high quality Japanese tools materials and techniques.

White Paper Steel (Shiro Gami)
The finest grain:
Non-alloy Japanese carbon steel, finest martensitic structure. Extremely sharp, close to sword steel. With heat treatment instructions. (C = 1,1 - 1,2%, Si = 0,1 - 0,2%, P < 0,025%, S < 0,004%)

4.5 x 30 x 500 mm.

29.60 &#8364;incl. VATper piece

They also sell bars of San Mai with white or blue cores.
(I plan on trying that when I need to order new steel)

Japanese Multi-Layer Steel, medial layer "Blue Paper Steel"
(C=1.2%, Cr=0.4%, W=1.8%)
somewhat tougher and more wear-resistant (carbide formation) than white paper steel, with a slightly coarser grain.

Close to the sword: Japanese Multilayer Steel "Katana"
For the first time, we are able to offer Japanese multilayer steel with a composition that comes close to that used frequently in Japanese swords (Katana). The high carbon core layer does only extend to the middle of the blade's profile. Multiple layers of softer steel folded on either side make this metal virtually unbreakable with excellent cutting properties. This type of construction also minimizes the risk of cracking during hardening. Usually the steel is forged further, but a blade can also be ground from the steel directly. The material is supplied unhardened; instructions for heat treatment included (final hardness 62 Rockwell).

5.5 x 35 x 380 mm.

EDIT:
This is the one I plan on trying:
apanese Multi-Layered Steel (Takefu Suminagashi)
the finest 22-layer Sumionagashi steel with a medial layer of "white Steel." The multi-layer steel can be ground or forged and then hardened to produce blades of both incredible sharpness and resilience. Flat steel, not stainless. Supplied unhardened with heat treatment instructions.

5.5 x 33 mm x 1 m.

63.30 &#8364;incl. VATper piece

But with the $/&#8364; extange rate and shipping cost it might get expensive
