Bohler N680, is a highly corrosion resistant steel, with high Chromium content as well as Nitrogen, improving it's corrosion resistance. It can be compared to H1 - it's not quite as corrosion resistant, but holds its edge a better than H1. It is imported from Austria.
0.54% Carbon (C), 17.30% Chromium (Cr), Manganese 0.40%, 1.1% Molybdenum (Mo), Nickel 0.50%, Nitrogen 0.20%, Silicon 0.45%, 0.10% Vanadium (V).
Bohler N690, the equivalent of 440F, which is 440C with a bit of Cobalt. Some compare it in performance to VG-10. It is imported from Austria.
