I found it on the matweb and it is 0.6% - 1.4% What is real or average carbon persentage there??? I plan to get it from McMaster. Any ideas how to determine carbon in the steel +\- 0.1% ???
 
W1 used to be available in a wide range of carbon content but most all of it now (drill rod) is around 1%, which is about perfect for blades.
 
Precision ground W1 appears to be available from Diehl. Can hamons be manipulated from W1? Thanks
 
Hello Danbo: I thoought that W2 was one of the best for showing hamons. Maybe I am mistaken and that all steels provide good hamons. ???
 
Before you buy ask the supplier for the carbon content ! .80-1.00 would be the best for you.
 
Hamons are easiest on shallow hardening steel. The lower the manganese content in simple carbon steels the more active it will be. When you start adding alloying elements like chromium and higher manganese it makes it harder to get distinct and active hamons.You can get a quench line in most steels if they are quenched in oil or water but these are not true hamons. W2 and 1095 are shallow hardening steel and can give good activity.
 
Dmitry,

Cincinnati Tool Steel has W1 in DCF (decarb free) as opposed to the usual P&G (polished and ground) for making drill bits, etc. It comes in squares/flats from 1/16" up. The W1 they carry is 1.00% C type. Here's the web site but you will likely need to call. http://www.cintool.com

I found dealing with tool steel houses easiest if I could give them sizes and lengths wanted. If you want 10# the price will be different than if you want 100# or 1000#.

For got to say... if you want the batch chemistry for the steel you are buying, just ask for it... you can even ask that your steel be all from the same batch.
 
Thanks Mike, I checked cintool cite and found that they have W2 steel only. But thanks i might try them if the prices will be right.

Strangely but in their own datasheets it says that W2 steel has a 0.95-1.1% variation of carbon. Not the 1.00% definitely...
 
Dmitry,

I went to CinTool.com, too. I had forgotten the site only lists W1 under "Drill Rod" (a precision ground form). I have a CinTool catalog and that is where the W1-DCF is shown... they do have it. A catalog can be ordered from the "Catalog" link page... top-right of that page... or a person could call them.

I originally got to Cincinnati Tool Steel because I was looking for W2. Jerry Rados sent me there because that is where he was getting his W2. That was over two years ago.

I have never really understood why some supplier sites list steel chemistry as a range. Heat Treaters Guide lists W2 carbon range as 0.85% to 1.50%. So, historically, W2 was available through that range... different carbon chemistry for different end-use. I think what you see as a wide range of carbon in CinTool W2, isn't really. I "think" their listing it that way is designating the sub-range within the total carbon range of W2... because there is such a wide range possible. To me, the 0.95% to 1.05% C listing says "1.00% C... give or take".
