N690 is an extremely ubiquitous and popular steel among knifemakers in Europe. Strength and toughness are comparable to that found on VG-10 or 154CM. This steel has extremely good corrosion resistant properties.
Best Knife Steels in 2021 (Steel Charts & Guide by a Marine)Steel type:VG-10 / N690. Common Use Case:When you want the quality of 154CM steel but need a little more corrosion resistance. Blade Hardness:59-61HRC. Sharpening Difficulty:Medium 5/10 Edge Retention:Good 7/10 Corrosion Resistance:Very good 8/10 Toughness:Good 7/10

IntroductionOther DesignationsMachinabilityHardeningWeldingHeat TreatmentForgingAnnealingTemperingMartemperingCold-work tool steels are high carbon steels that are further classified into three subgroups such as oil-hardening steels, high-carbon, high-chromium steels, and air-hardening steels. Oil-hardening cold-work steels are also known as group O steels consisting of O1, O2, O6, and O7 types. Type O1 oil-hardening cold-work steel consists of chromium, manganese, and tungsten and is relatively inexpensive. The following datasheet provides details about O1 type.Steels introduction information on various knife steelsN690 is sometimes compared to 440C steel. Many knife makers however do not believe that 440C is the best steel for comparison to N690. N690 is a much better steel and it is very similar to the VG10. N690 steel is so good for making knifes that many prominent knife manufacturers use only N690 steel.
STEEL WILL - N690CoN690Co. N690Co is an Austrian steel that is often compared favorably against 440C. Depending on heat treatment it may have equal or better wear resistance and toughness.
Steel Information - CASiberiaThe very high carbon content allows the steel to be quenched to the mid-60's HRc and drawing back to 58-60 HRC produces a tough blade with superb edge-holding properties. D2 Steel Composition:1.50C 0.6Mn 0.6Si 11.50Cr 0.30Ni 0.95Mo 1.1V

Stellite 6-KThe 10XX (1045, 1095) Steels - 1095 is the most common 10XX steel (or \"high carbon\" steel) used for knife blades. Steel in the range 1045-1095 are used for knife blades, although 1050 is more commonly seen in swords. 1045 steel has less carbon (.45%), where 1095 has more (.95%), inversely 1095 has less manganese and 1045 has more. So in essence, 1095 steel would have more wear resistance, but would also be less tough. 1045 holds an okay edge, 1095 steel holds an edge great, and is easy to shaNICHTROSTENDER STAHL STAINLESS STEELBÖHLER N690 EXTRA ist BÖHLER N690 ISOEXTRA, produziert nach dem Elektoschlacke-Umschmelzverfahren (ESU).
