Among its most common uses include the production of metal sheets, boxes, pipes, chains, wires, cases, rivets, vehicle frames, etc. It is also used frequently in saw blades, but any knife made from this material needs consistent maintenance. It typically has .98-1.10% carbon. There are some reports that when the first Damascus steel was encountered it would cut through the sword blades that the Europeans were using. They should, though. What Are the Types and Properties of Steel? See As with most strengthening techniques for steel, Young's modulus (elasticity) is unaffected. Strength and hardness are higher than low carbon steel, and plasticity and toughness are lower than mild steel. This steel often gets compared to ATS 34 because the two are so similar. This type can be molded into different shapes, making them ideal for use in engine components and nuclear waste casks. This is a low quality steel, comparable to 420. Stellite is a special material that has no iron in it. High carbon steel has a greater than 0.55 percent carbon content by mass, Since not all of us have the basic training of a materials scientist, here are a few key differences in steel types that will help you decide what type of blade is best for you. This steel holds an edge really well. Nickel steel offers incredible responsiveness to heat treatment as the addition of nickel lowers the steel’s temperature, making it ideal for heat treatment. However, the high degree of hardness makes this steel difficult to sharpen. The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. O2 is another reliable high carbon steel. It is wear resistant, and it is a hard steel. Form or shape: Bar, Rod, Tube, Pipe, Plate, Sheet, Structural, Etc. In addition, in the SAE system any steel starting with a letter is classified as tool steel. While knife makers could debate at length about the benefits and drawbacks of using different steel grades to forge blades, the reality is that most people don't really pay much attention to the grade of steel used to make a knife. US ASTM SAE AISI 1030, 1034, 1035, 1038, 1040, 1042, 1043. High carbon steel has high strength and hardness (Rockwell C can be up to 60-65 HRC), high elastic limit and fatigue limit after proper heat treatment or cold drawing hardening, and the cutting performance is acceptable, compared to low carbon steel and medium carbon steel, its weldability and cold plastic deformation is the worst. S30V Steel – This steel was designed to be used for knives. Blade Steel Types.URL:, Joe. Nickel steel alloy is among the most commonly used steel alloy around the globe. The medium carbon steel after quenching and tempering has good comprehensive mechanical properties. This is also the type of steel used most often for surgical applications. It is low quality, low cost material. For a more up-to-date guide to knife steel, check out our Ultimate Blade Steel Resource. They are often used for producing wrenches, arbors, and taps. It holds an edge really, really well, but it can be brittle on large knives. This feature means that the tools produced do not crack easily. If you have ever watched the TV show Highlander, you have probably heard of Damascus steel. High carbon steel typically contains around 0.61% to 1.5% carbon content, resulting in strong, brittle, and hard steel. All treatments of steel trade ductility for increased strength and vice versa. Among its properties, saturation reduction, resistivity, magnetostriction, and magneto-crystalline anisotropy are highly sought out. 440A is used in many production knives because of its edge retention, ease of resharpening, and corrosion resistance. It holds a good edge and is fairly easy to resharpen. High-carbon stainless steels, this grade of stainless can be hardened to a greater degree than 420-grade steel, allowing for greater strength and wear resistance. This steel is comparable to 440C. This involves rolling the steel between two polished rollers under high-pressure conditions. Accept Your email address will not be published. Plain carbon steel contains no appreciable alloying element other than carbon itself, and, depending on the carbon content, is classified as low-, medium-, or high-carbon. This material is really, really hard so it almost never needs to be sharpened. Besides being used for high strength wires and springs, it is a useful material for producing shock-absorbing machinery. Carbon Steel 2. However, it can be almost impossible to sharpen. [1] Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components. The World Material is a website mainly provides the information of worldwide material grades, including US ASTM AISI SAE, European EN, British BS, Germany DIN, France NF; Japanese JIS and Chinese GB Standard, so you can learn and compare the material datasheet and specification of the major countries. 154 CM Steel - This is high quality steel. Because it is highly malleable and can be molded into a variety of shapes and sizes, this type is the most commonly used among the three. Yet, it’s not strong magnetically. High-tensile steels are low-carbon, or steels at the lower end of the medium-carbon range,[citation needed] which have additional alloying ingredients in order to increase their strength, wear properties or specifically tensile strength. The medium carbon steel is mainly used to manufacture high-strength moving parts, such as air compressors, pump pistons, steam turbine impellers, heavy machinery shafts, worms, gears, etc., surface wear parts, crankshafts, machine tools spindles, rollers, bench tools, and more. However, the 400 series are some of the most rust resistant knives out there. It has a carbon content range of .85-1.00%. Carbon steel is a steel with carbon content from about 0.05% up to 2.1% by weight. Types of Carbon Steel. As the main alloying element of carbon steels, carbon accounts for around 90% of all steel production. It comprises iron, carbon, and varying specific amounts of other alloying elements. The addition of chromium lowers the critical cooling rate and increases the scaling resistance, wear resistance, and high-temperature strength of steel. Even though austenitic steel is unresponsive to heat treatments, it is popular for its non-magnetic properties, making this steel one of the most widely used steels worldwide.
