N690
N690 is cobalt enriched stainless steel from the Austrian manufacturer Bohler-Uddeholm. The N690 steel is similar in its parameters to the 154CM steel or the Japanese VG-10 steel. N690 is a high-quality stainless steel with a hardness of 58 - 61 HRC and very good edge retention. It is not as hard as premium super-steels, but its hardness is above average and absolutely sufficient for ordinary users. The big advantage of N690 steel is the easy sharpening and toughness (edge is not brittle). Excellent steel for outdoor knives, hunting knives and for EDC folding knives.
Steel composition: 1.08% carbon, 17.3% chromium, 1.5% cobalt, 1.1% molybdenum, 0.4% silicon, 0.4% manganese, 0.1% vanadium.
