Another Russian one, R12F3 high speed tool steel. Equivalent of the W-Nr 1.3318 or DIN S12-1-2 steels.

9X5VF steel composition added. Russian version of the AISI A2 tool steel. Unlike western counterparts it has 0.80%-1.20% Tungsten(W) added to it. Although, it looks more significant in mass percentage than in molar mass, which translates into ~4-6 atoms to Tungsten per 1000 atoms in the alloy.

Added Russian SHKH20SG steel, also known as SHH20SG, which is listed by its manufacturer as an equivalent all of the following AISI 52100Mod2 steel, AISI 52100Mod3 steel, AISI 52100Mod4 steel.

Frankly, i'd rather not have to have doing updates like this. Wile researching ceramic knives and that included them, stumbled upon bunch of consumer complaints about their tactics luring customers into buying more items, but at much higher price. Short summary, stay away from their website, and better yet, their knives, but if you insist, it's safer to buy those on ebay. Also added more details on ceramic materials used in various ceramic knives.

Russian SHKH15 steel composition added, which is an analog of the AISI 52100 steel. Slightly less carbon and more chromium in SHKH15, no copper unlike 52100.

Found on one of the Russian steel manufacturer's site and also some Euro knife forums mention it. R12 high speed steel, which can be described as Tungsten-Vanadium high speed steel, but no direct analog in western steel making. The closest by composition that I could identify was the German W-Nr 1.3211 high speed steel. However, Russian R12 has only 0.50% Cobal, while western counterpart has 2.60% of Cobalt.

Corsair tool steel, which I've just discovered on Latrobe site is an equivalent of the AISI M3:1 tool steel. Pretty close to standard specs.

Stark steel is one more AISI M4 high speed steel version from Latrobe. They already have Duratech M4 steel, Duratech Mega 4. Although, Mega 4 has disappeared from Latrobe website.
