Yep as with anything in Steel making contends can vary.
Good Luck and show your results.

Japanese Swords can have anything between 0.5-0,8 its a question of period of Time and fashion of school and whats available.
But many Westerners like the 0.5 steel wile its easy and forgiving.

Hi,
have a look at this side
http://forums.dfoggknives.com/index.php?showforum=3
here you will find a lot about hamon and steel and the Forum has lots of Bladesmithing and Knivemaking
Look also for Verhoefen he wrought a lot about hardening of Knife steel,thare must be an dread to it.

Hi their,
yoop 1% isn't much,in the most spring steels Si ore Cr are the sinners when it cams to deep hardening. Si can make it even Air hardening and it doesn't take that much of it.
If nice Hamons is all you wont, than the German steels you fount work well. With practice that is ;)

Sorry,
I don't buy Steel, i'm a take it were it cams from guy
But you can have a look here http://www.messerforum.net/ there must be a topic about were to get Steel. Just cut not find it.
You may also ask for the german W1 cors i dint find it yet.
hey your German i not bad.

Ok hier it is
just as i remember

W = Werkzeugstahl
W1, W2, W3 = Werkzeugstahl 1. 2. und 3. Güte
WS = Werkzeugstahl für Sonderzwecke

can you read German?

it maens 1-3 Qualitie or first ist best

The steels you showd ar simbel Toolsteels without much extra.
thou C80w1 is a very clean C80 steel und also hast .80 C
weil normel c80 can have .75-maybe .90 C
but i think i can finde the German W1 and give you its DIN number

Aha
but i cant see V ore T an the specs
thou W1 and W2 in the US can have any C between .8 and 1.0 ?
OK i gonna trey to find what the W1/W2 means in Germany
now i gotta know

Hi,
my English is not that good so have mercy with me.

I think you look at German Steel and there the W1/W2 has another meaning.
I cant quit remember put i think it says how clean and close too tolerance it is.
By the way, this Steel are only shallow hardening when they are thicker. Over 15 mm ore thou. If you make a blade of say 10mm it will harden all the way threw.

Hi

their is a vid on You Tupe of a guy forging a Titanium Blade its nice, but you cant weld titanium the forgeweldway.

Also it's not gut for swords, i think the most Ti is way to soft only the surface will get hart.


Mod note: this statement is not exactly coprrect as Ti has been forge welded, see Timascus
