N690 Steel Properties
The N690 Cobalt Stainless Steel is made in Austria by a company known for making steel that can be made into
sharp knives and surgical instruments. It has 1.07% carbon content.The N690 is a high-end stainless steel with an
alloy that is common in many good knives. It is a durable knife steel that is wear-resistant. It is also a very hard
This steel contains the important martensitic chromium steel with cobalt, molybdenum, and vanadium. This steel
can be hardened to a very desirable hardness level. The surface finish is finely ground or polished.
N690 Bohler Steel is extremely fine grained creating a blade that will retain its sharpness when subject to periods
of use. Let’s face it, all blade experts will tell you that the finer the steel grain – the better the edge retention. By
adding cobalt, an extremely unusual alloying element, an extra edge is provided. Having cobalt mixed into the
steel creates an uncommon uniformity providing a fine and consistent edge, enhancing edge retention and
Coming from Arno Bernard we feel we can safely argue that the edge-holding ability of N690 is superior to most
They are also heat treated and tempered using a liquid nitrogen process. This leads to a staggering hardness and
ability to resist deforming when subject to stress and applied force. N690 is once again the winner of steels by
resulting in a blade that is 59-60 on the Rockwell hardness scale.
