D2 and Sleipner are somewhat similar because they are in the same cathegory of semi-inox steels, however....
the chemical compositions are quite different, and this is reflected in a very different response in terms of performance.
D2 chemical composition:C=1.55%, Mn=0.3%, Si=0.3%, Cr=12%, Mo=1%, Va=1% Ni=0.3%
Sleipner chemical composition: C=0.9% Si=0.9% Mn=0.5% Cr=7.8% Mo=2.5% V=0.5%
D2 has more Chromium, it reduces a lot the resilience of this steel (thoughness) making it just a bit thougher than inox steels. it's about 30J/cm^2 at an hardness of about 60 hrc.
Sleipner instead at the same hardness has a resilience superior than the one of A2 tool steel, it means about 60 or more J/cm^2 so the resilience is the double.
D2 has more carbon and chromium, this gives D2 an higher abrasive wear, which translates in a steel hard to sharpen. field tests prove it.
Sleipner is easier to sharpen A LOT.
the corrosion resistence is pratically the same, in my direct experience Sleipner proved a bit more corrosion resistent in humid conditions and sea water than D2.
edge holding: Sleipner wins, for sure.
maximum sharpness achievable Sleipner due to a finer grain structure.
in the particular case of Kniferesearch the heat-treats will be done maniacally, so you can stay sure the steel will revail all it's potentials
in conclusions... I've tested both, liked sleipner more, that's it.
I repeat, I have no interest and have no direct connections to kniferesearch, but I'm a collector who loves to use his blades and I've just given my experience, impressions and knowledge to you.
hope this helps.![]()
Thank you for the explanation
How would you compare Sleipner to Viking?
