Oct 19, 2021 · Therefore I will be showing the ratings of the steels graphically in terms of toughness-edge retention balance, where steels that are high and to the right have the best combination, and you choose the steel based on the level of toughness or edge retention necessary for the knife.
Here we collect the metal strength chart (tensile, yield strength, hardness, and density included) and mechanical properties chart of common metals of different grades for your reference.

Aside from carbon and iron, carbon steels contain only trace amounts of other components. Carbon steels are the most common of the four steel grades, accounting for 90% of total steel production! Carbon steel is classified into three subgroups based on the amount of carbon in the metal: 1. Low carbon steels/mild steels (up to 0.3% carbon) 2. Medium...
Alloy steels are made by combining steel with additional alloying elements such as nickel, copper, chromium and/or aluminium. Combining these elements improves the strength, ductility, corrosion resistance and machinability of the steel.
Stainless steel grades are alloyed with 10–20% chromium as well as nickel, silicon, manganese, and carbon. Because of their increased capacity to survive adverse weather these steels have phenomenally high corrosion resistance and are safe to use in outdoor construction. Stainless steel grades are also commonly used in electrical devices. For examp...
Tool steels, as the name suggests, excel in cutting and drilling equipment. The presence of tungsten, molybdenum, cobalt and vanadium helps improve heat resistance and general durability. And because they hold their shape even under heavy use, they are the preferred material for most hand tools. Learn how tool steel is made here!
The molecular structure of pure iron at normal temperature is referred to as ferrite. This microstructure will also be found in steel with very low carbon content. A body-centred cubic (BCC) crystal structure is the ferrite’s distinguishing feature. The molecules in BCC are more loosely packed than in other microstructures that contain more molecul...
Austenite is a microstructure generated when iron-based alloys are heated over 1500 degrees Fahrenheit but below 1800 degrees Fahrenheit (982 degrees Celsius). If the correct alloy, such as nickel, is present in the steel, the material will retain its microstructure even after cooling. Austenite is distinguished by its face-centred cubic (FCC) crys...
When carbon steel is heated to austenite temperatures and subsequently cooled without any alloy present to maintain the austenite shape, the microstructure reverts to ferrite. However, if the carbon level exceeds 0.006%, the excess carbon atoms bond with iron to create iron carbide (Fe3C), also known as cementite. Cementite does not form on its own...
Pearlite is a laminated material composed of alternating layers of ferrite and cementite. It happens when steel is progressively cooled, generating a eutectic combination. A eutectic mixture occurs when two molten materials crystallise at the same time. Under these conditions, ferrite and cementite form concurrently, resulting in alternating layers...
Martensite has a tetragonal crystalline structure that is body-centred. This microcrystalline form is achieved by rapidly cooling steel, which traps carbon atoms inside the iron lattice. The end product is a needle-like iron and carbon structure. Steel with a martensite microcrystalline structure is typically a low-carbon steel alloy with about 12%...
To prevent corrosion, molten steel must be shaped into its final shape and then finished. Steel is often cast in machine-ready shapes such as blooms, billetsand slabs. Rolling is then used to shape the casts. Depending on the material and intended application, rolling can be done hot, warm or cold. Compression deformation is done during rolling by ...
