Did anybody here tried X12BM - russian steel invented in 1964.

Look at this composition:

C=2-2.2 Si=0.1-0.4 Mn=0.15-0.45 Ni<0.35 S<0.03 P<0.03 Cr=11-12.5 Mo=0.6-0.9 W=0.5-0.8 V=0.15-0.3 Cu<0.3

Usually it refered as an Russian D2, but honestly this is quite different steel - much more carbon and in addition molibden, tungsten...

I know Kizlyar making knives out of it, but here they sell only stainless steel models.

Thanks, Vassili.
 
Wild. Do you know what this tends to be hardened to? Can you show us any knives using this stuff? I'm really curious to know how this performs.
 
Don't get too excited. It's D4 which is essentially high carbon D2. The Europeans use this and North America does not. It's a tooling material. As for the copper, all steel has it but it is kept to low levels due to its detrimental effects in higher quantities.

Do you know where in Europe (I don't think you mean Russia, for some reason that half of Eourope never called this way) I can buy it - ether knife of steel blank? And what is the name of it in Europe - I doubt they call it D2, should be something like X22CrMoVW... ?

Thanks. Vassili
 
Bohler sells K107 which is DIN 1.2436 or X215CrW12.

D3 is also very popular and is nearly identical to D4. Bohler K100 DIN 1.2080 or X205Cr12KU.

If memory serves me K100 is used for planer blades etc and is more available.
