Description
D2 tool steel first emerged during the World War II era. 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. The basic formulation of this steel is as follows—carbon 1.40-1.60 percent; chromium 11-12 percent; nickel 0.30 percent; magnesium 0.40-0.60 percent;

  D2 Steel Blades - Knife Review  -By Alta Special Steel D2 tool steel first emerged during the World War II era.

It can be difficult to!olish !ro!erl, with man manufacturers o!ting to avoid attem!ts at mirror !olishing sim!l because it takes too much time and effort with little to gain.7urthermore, since D2 blades are t!icall -ockwell hardened to -0 (&'($,some users will encounter difficulties with edge reestablishment. At the sametime, once a D2 blade has been shar!ened !ro!erl, it will hold its edge muchlonger than blades with a lower -ockwell hardness. hat is 8ust one of thenormal trade'offs between steel allos.094'D2:ome time ago, the folks at 0rucible !roduced a small run of 094'D2 usingtheir !ro!rietar 59article 4etallurg6 !rocess. he !ur!ose of using this!rocess was to make a blade steel that had fine grain structure, im!rovedfinish, enhanced toughness and was easier to machine and grind. ince this!rocess !roduces molecular elements that are more consistent in size, theresult was a more homogeneous distribution of the various chemicalcom!onents within 094'D2. 9otentiall, this could lead to a finer and moreconsistent cutting edge as well as better edge retention. 3owever, when oucom!are a regular D2 blade with the finer edge found on a 094'D2 blade, ithas been found that the somewhat 5tooth6 cutting edge from the larger !resence of chromium and vanadium carbide/ of the D2 blade offers extendedfunctional !erformance. In the end, which version works best for ou made!end on what ou intend to cut. A tooth edge is useful for hide and flesh,but a smooth, !olished cutting surface has advantages for woodworking andcutting fish.  When it comes to toughness, 094'D2 has the !otential of being a little moreductile than regular D2. ince the actual in'the'field !erformance differencesfunctional edge retention and shar!ening ease/ between regular D2 and094'D2 have not !roven to be significant, cou!led with the increased cost of 094'D2, regular D2 has remained the blade steel of choice b manufacturersand custom makers alike. While D2 blade steel will rust and stain ;uicker thanan of the stainless blade steels, its elevated chromium content does offer enough resistance to environmental attacks to garner it the title of 5semi'stainless.6 With minimal care, D2 can remain free from corrosion and stainingfor the lifetime of the blade. 7urthermore, the vanadium content of D2!rovides enhanced edge retention, which makes it historicall su!erior bladesteel. 7or these reasons ou’ll find D2 blade steel used in the knife inventoriesof <ueen 0utler, Dozier =nives, imberline and man other manufacturersand custom makers. D2 is a fine exam!le of the old saing: 5If it’s not broke,don’t fix it.6hould ou have the occasion to browse through an retail location that sells hunting gear, ou’ll most likel encounter ammunition'reloading su!!lies.  Among the boxes of new brass cartridge cases, !rimers, bullets and related !ara!hernalia there will be an assortment of various !ro!ellants. >ven though some of these !owders have been recentl develo!ed, man of the more !o!ular ones have a long histor of use going back for decades. ?ikewise, des!ite the more recent develo!ment of several stainless formulations, some of the blade steels in use toda also have rather historical lineages. Alta !ecial teel is good at su!!ling D2, A2, @$, %2&, %2&30, %%&A etc toolsteels. ust contact us to get the B> raw materialsC ' salesaltas!ecialsteel.com.@- recommend our steels to our makers.
