They will take and hold an edge much better. All that is needed to make basic steel is a combination of iron and carbon. Many cheap knives tend to be made of this material because of its cost. Its major problem is that it rusts rather quickly if it isn't maintained. So as you can see, "high carbon" is a relative term. Blade Steel Types.URL: www.theknifeconnection.net/blade-steel-typesTalmadge, Joe. It is the most rust resistant of 440 steel, and 440C is the least rust resistant of the three. Properly heat-treated, O1 and 1095-grade steels are seen as by many equal to any expensive stainless steel grades. 52100 Steel - This is high carbon tool steel. The AUS Series (Japanese Stainless Steel): The biggest improvement of the AUS series over the 400 Series is the addition of vanadium which improves wear resistance and gives good toughness. A high chromium content stainless (14 percent) that contains molybdenum and vanadium, which enhances the toughness, corrosion resistance, and edge holding ability. Blade HQ uses cookies to provide you a better user The 10XX (1045, 1095) Steels - 1095 is the most common 10XX steel (or \"high carbon\" steel) used for knife blades. Stainless steel has a comparatively low carbon content -- usually 0.08 percent. In contrast, alloy steels have a specified composition and contain certain percentages of vanadium or molybdenum, and they also typically have a larger amount of manganese. 0-1 is an oil hardening (cold work) die steel that can be hardened at relatively low temperatures. These added elements account for what is the major difference of most types of steel in blades. It has good edge retention. This material is used often for hunting knives. Cutlery-grade stainless generally contains more than 13 percent chromium, the oxide of which helps to form a passive film that protects against corrosion and staining. This is also the type of steel used most often for surgical applications. This type of steel is also very difficult to mirror polish, so you will almost never see it. The M20 Grade 8.8 Galvanised Bolts are dipped into the galvanizing solution and get a galvanized coating. The low carbon content means that it’s very soft in comparison to most others, and it … So in essence, 1095 steel would have more wear resistance, but would also be less tough. It has a carbon content of 1.45%. Grade 420 stainless steel is a high-carbon steel with a minimum chromium content of 12%. It will often be coated on a knife blade to avoid this issue. One piece 425 high carbon stainless construction. O6 Steel - This is a much tougher metal than 0-1. Terence Bell wrote about commodities investing for The Balance, and has over 10 years experience in the rare earth and minor metal industries. It is just a step above S30V. It actually has pretty good toughness for how hard the steel is as well. Slightly less corrosion resistant than 440A, 440C is more widely used and is better regarded because it takes and holds a sharp edge, that is tougher and more stain-resistant than ATS-34. Currently, this steel is not commonly used. If you have collected knives for a long time, or even if you are new to knives, chances are you have wondered what the differences are between all the types of steel in knife blades. CPM 3V Steel This steel holds an edge really well. It is much tougher than most stainless steels, but not as tough as most of the other tool steel. Includes a hard plastic sheath. It is wear resistant, and it is a hard steel. It is the most stain resistant steel on the market, and is a hard material. However, like other non-stainless steel it rusts easily.

Buck) can really bring out the best in this affordable steel using quality heat treatments. These grades of Japanese stainless are comparable to 440A (AUS-6), 440B (AUS-8), and 44C (AUS-10). So, this means that 1095 steel would be .95% carbon. It also has decent toughness for a tool steel. Generally considered the king of the 420 steels, 420HC is similar to 420 steel but with increased levels of carbon (HC stands for High Carbon) which makes the steel harder. If you are not sure about the type of steel used…there are some coming from China that use different designations for steel type…type it into a search engine and look for it. Once heat treated it becomes extremely hard and brittle. It's carbon that makes carbon steel hard enough to use as a knife blade. Midway USA. Very similar to the ATS-34 and 154CM grades but with a higher vanadium content, this steel behaves equally as well but with more stain resistance and toughness. It is low quality, low cost material. Each of these types of steel has a designation system that gives them a specific number. 440A is used in many production knives because of its edge retention, ease of resharpening, and corrosion resistance. It has a carbon content of 1.05%. The low carbon content means that this steel is very soft, and doesn't hold an edge well. It has a carbon content range of .85-1.00%. Includes a hard plastic sheath. 425 Mod, and 440A GENERAL PROPERTIES Types 410, 420, 425 Modified, and 440A (see composition on Page 2) are hardenable, straight-chromium stainless steels which combine superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. However, the 400 series are some of the most rust resistant knives out there. This is one of the most wear resistant tool steels. 440C Steel - This has a carbon content range between .95-1.20%. Pushing this content past 2 percent makes the result extremely brittle and of limited use, although this is how cast-iron products (e.g., wood stoves, cookware) are made.
