Most Scandinavin manufacturers seem to use Sandvik 12c27 for thier stainless and they say so, however for their non stainless usually they say just " high/ plain carbon steel" or something like that. Is there a " standard" carbon steel used and what is the typical carbon content?
Yes I know heat treatement matters and I know Roselli's "speciale" UHC is 1.5 - 2% carbon (I find a stated range of +/- .5 % strangely wide and not helpful but whatevere), I am just interested in the "typical " steel used in Scandi knives- if there are differences then I woulde be interested in ones used by Frosts, Jarvenpa, Kellam, Erickson, etc, the most familiar co's.
Thank you and happy new years

Thanks for the informative links but I want to just know what " standard" carbon steel is used in Scandi knives- does any one know?????? :confused:
 
I would assume it depends on who is making them, Eriksson uses 1095 according to Ragnar, all the ones I have seen act similar.

Reference Steel Composition sites. Checked two other steel composition sites and for 12C27 they both list 0.58-0.6 for carbon, not 0.25. For 13C27 it is 0.65 and for 19C27, 0.95 carbon. I got the same information on 12C27 from EKA. I corresponded with Jukka Hankala about his carbon "Silver Steel" (Finnisch Hopeateras). He said it was made by Boker, called K510 and has 1.18 C, 0.7 Cr and 0.1 Vanadium. Rauno Vainionpaa, another Finn, uses something similiar to AISI 1080. Both are custom makers so, just like in the U.S.A. different makers and factories will use different steels. Try emailing them, I did with Helle Knives and they sent me the composition of their hard inner core of their laminated stainless steel.
 
The most basic steel used (by Finnish makers) would be a carbon steel with 0.6-0.75 per cent carbon. But different steels are available. The Hopeateräs mentioned above, Böhler K510 (use the site's search for datasheet) is one that's popular. 1085-1095 equivalents are common, sometimes with small amounts of vanadium or chromium. Swedish steels (SMT) and steels made in central Europe are also largely imported.
 
Thank yo John and Way-O, just the leads I wanted, I will follow up from here- thank you and happy new year -Martin:thumbup:
 
As I understand there steel type is not used in marketing as it is in US. Mostly it is Stainless and Carbon and it is whatever they were able to buy on the market currently.

Stainless is usually Sndvic 12C27 (C=0.6 Cr=14-14.5 Mn=0.35 Si=0.35) from Sandvic ore deposit - gift from the nature to scandinavian metallurgists, has no Sulfur ann Phosfor in composition. KaBar Next Generation was designed to be from 12C27, also Bark River use it as an stainless option for some of their models.

There are also 13C26 (C=0.65 Mn=0.65 Si=0.4 Cr=13.0) and 19C27 (C=0.95 Mn=0.65 Si=0.4 Cr=13.5). Kershaw Storm is made from 13C26.

Also it may be Marss-5000 (C=0.52 Cr=14.5 Mn=0.6 P=0.025 Si=0.4 S=0.01) - by Uddeholm cheaper version as I understand. Lauri uses it.

And of course on the top RWL-34 (C=1.05 Cr=14 Mn=0.5 Mo=4.0 Si=0.5 V=0.2) by Soderfors - as I understand powdered version of ATS34. Crucible just start making same - CPM-154.

And powdered UHB Elmax (C=1.7 Mn=0.3 Cr=17 Si=0.4 Mo=1 Va=3).

Carbon steels:

UHB20C /1870 (C=1.0 Mn=0.4 P=0.02 Si=0.3 S=0.015) - widely used as component in damascus blades

UHB17VA (C=0.85 Cr=0.54 Mn=0.55 P=0.02 Si=0.3 S=0.02 V=0.2) - Lauri uses it.

Custom makers in Finland uses Silver steel which may be - Bohler K510/DIN 115 CrV 3 (C=1.18 Cr=0.7 V=0.1) or other composition I saw Silver Steel by Peter Stub Limited (C=1.1-1.2 Si=0.1-0.25 Cr=0.4-0.5 S=0.035 Mn=0.3-0.4 P=0.035)

Roselly Carbon steel (not UHC just regular Carbon, basic models) is W75 by ThyssenKrupp. UHC is probably made in house, somehow.

Thanks, Vassili.
 
The 'silver steels' sound like kissing cousins to 50100B and 52100, two of my favorite high carbon steels.
