Also early in that period they developed high speed steels which used Cr-alloying rather than Mn-alloying for hardenability, where they used about 4% Cr. Our suppliers seem to treat them all as the same, but K110 from bohler does not always do what the datasheet says it should… typically my results concur very well with the datasheets… so it makes me wish for an inhouse hardness tester so i can verify hardness with every batch of steel i get. However, tungsten was expensive and difficult to obtain leading to the use of high chromium steel as an alternative. Hunting Knife- D2 Steel with Rosewood Handle- 16" Share this Product. D2 Steel D2 steel is the perfect balance between performance and accessibility. [6] Wills, W. H. “Practical Observations on High-Carbon High-Chromium Tool Steels.”, [10] Schruff, I., V. Schüler, and C. Spiegelhauer. As this nation’s wartime efforts moved from individual craftsmen working with their hands to mechanization, the inherent toughness and excellent wear resistance found in D2 allowed it to be widely used in stamping dies. However, there is an asterisk next to the S35VN value and if you follow that down it says, “Estimate based upon market feedback.” In other words, they didn’t actually measure it. 100% (7) 0% (0) 0% (0) 0% (0) 0% (0) J .

The chromium-rich alloy carbides in the D2 steel create excellent resistance to wear from sliding contact with other metal or abrasive materials. In 1918 a patent was filed in England by Paul Kuehnrich [5] for a high carbon high chromium steel modified with cobalt, approximately 3.5%. A Genuine Hand Stitched Leather Sheath. I would expect the toughness to be similar to other D2 assuming the heat treatment is done correctly.
