PMC27
(0.6% Carbon (C), 13.5% Chromium (Cr), 0.5% Manganese (Mn), 0.5% Silicon (Si)) A very pure powder steel, which although not available as a steel on its own, is used together with RWL34 steel as an additive in DS93x damascene. With its pure structure it can hold a razor blade excellently. It is very similar in composition to 12C27, but made by powder metallurgy which gives the steel an edge. Typical Rockwell hardness up to 64HRc. Germany / ZAPP
