CTS-BD1, high-carbon chromium steel that provides stainless properties with high hardness and excellent wear resistance. V-1/V-2 Chrome is added to improve quenching performance. improves machinability and resistance to corrosion. VG-7/VG-8W, strengthens substrate and improves tempering performance. DSR1K11, a steel known to exist. 420 series contain several types with various carbon content between 0.15% and 0.40% this steel grade is widely used to make high-end razor blades, surgical scalpels, etc. Adds strength, toughness, and improves hardenability. The following formula is a break down in the steel: Around 13% chromium and 5% carbon. Holds an edge better than it’s 400-series counterpart 420HC but at the expense of some corrosion resistance. Its 420HC steel blade contains modest amounts of Carbon, (0.40-0.50), that coupled with Buck's quality heat treatment gives it decent hardness and wear resistance. Read More. W2, a tool steel that holds its edge quite well but not very tough. AUS-8a steel is very easy to sharpen to a razor edge but it will dull relatively quickly compared to high-carbon. AUS-8 is tougher but is still easy to sharpen and holds a good edge. AUS-8. Ceramic knives can be sharpened with silicon carbide or diamond sandpaper but chip when sharpened on a hard stone or lap. In China, Ahonest ChangJiang Stainless Steel developed 7Cr17MoV, a modified 440A, by adding more vanadium. Q. I have heard some disparaging remarks concerning 440A stainless steel, as compared to 440C,with regard to knifemaking. It is a martensitic stainless high speed steel that combines the tempering, hot hardness and hardness retention characteristics of M50 high speed steels, with the corrosion and oxidation resistance of Type 440C stainless. The hardenability of 440C is due to it having the highest carbon content in the 440 group. Improves strength, machinability, and hardness. V-toku1 / V-toku2, alloyed steel with W /Cr's original characteristics. Carbon steels have less carbon than typical stainless steels do, but it is the main alloy element. 416 is very similar to 410 with the addition of sulfur to improve machinability. These steels can contain 26% to 42% chromium as well as 10% to 22% nickel and 1.5 to 10% of titanium, tantalum, vanadium, niobium, aluminum silicon, copper, or molybdenum etc., or some combination thereof. M390 – Bohler M390 Microclean. The bulk material is harder than stainless, allowing them to hold a sharper and more acute edge without bending over in contact with hard materials. Tolerates less than ideal temperature control in forging and heat treating (As does 5160). Daido stainless tool steels used for kitchen knives and scissors. C $91.02. Prior to 2002, INFI contained 0.5% carbon, 0.74% Nitrogen, about 1% Cobalt, and about 0.1% Nickel. Shirogami/White-2 Tougher than S/W-1 but as not much Carbon content, thus slightly less hard. [citation needed] Böhler n695 is equivalent to 440C. C $21.63. Because of this, 440C is one of the most common stainless alloys used for knife making. Ceramics are harder than metals but more brittle. One of the more common stainless steels, and one readily available in lots of different places worldwide, AUS-8 is a decent all-around steel. Increases strength, wear resistance, and increases toughness. 420HC VS 1095 1095 is tougher and has lower corrosion resistance compared to the 420HC. Chinese and American stainless steels; the manufacturers are unknown with the exception of 14-4CrMo which is manufactured by Latrobe Specialty Metals. The harder ceramics may be used in composite form to make them workable. Laminating a harder steel between a softer one is an expensive process that to some extent gives the benefits of both types (see Damascus steel).
