With a chromium content of 12%, D2 – a tool steel – can certainly be classified as a stainless steel. Since its chromium content is right on the threshold, however, a little more care for the D2 wouldn’t go amiss. As an upper-tier conventional steel, D2 offers great edge retention and stability, though sharpening it takes a little effort.

CPM 154

CPM154 is the “Crucible Particle Metallurgy” version of CM154 offering the typical advantages of a CPM steel, including a very fine and homogeneous structure and increased alloy components. It is often used by custom knife makers in the US. Its composition and performance are absolutely identical to the powder-metallurgical RWL34.

CPM S90V is a “Crucible Particle Metallurgy” stainless steel, widely regarded as a “super steel” for its properties and performance. CPM S90V is a stainless steel to which vanadium and carbon have been added for exceptionally good wear resistance. The wear and corrosion resistance of CPM S90V make it an excellent candidate to replace D2 or other tool steels in applications where improved corrosion resistance is also of benefit.
