Steel is a mixture of iron with a small amount (typically less than 2%) of carbon. Increasing the amount of carbon makes high-carbon steel, which is harder and stronger, but more brittle.
Proteins
thermal and electrical conductivity
Many different types of steel makes good knife blades-I believe that stainless steels are most suitable for the majority of knife types though. Good edge retention (Tests indicates that stainless steels; if properly heat treated, has better edge retention then most high carbon steels), very high corrosion resistance, and sufficient toughness.
its one of the strongest shapes of all there in our bodies without triangles we wouldn't be able to move our upper bodies.
It depends on the type of stainless steel you are referring to. Austenite and ferritic stainless is not heat treatable in which case carbon steel could be made far harder. However..martensitic stainless steels are heat treatable in which case they could be made harder depending on the alloy contents. Generally the more carbon a steel contains, the harder it can be made. Chromium; a key ingrediant in stainless steels, can also increase hardenability.
Tetravalence, Carbons ability to form four bonds with other atoms
Carbon makes molecules of all sorts. Just about anything that grows has carbon molecules in many parts of their bodies. Just one example is sugar. In one form, Sugar is the food for the brain.
Heat makes metal more malleable.
The ability of each carbon atom to form covalent bonds, including bonds to other carbon atoms. This makes possible chain hydrocarbons of any length.
Carbon has 4 valence electrons, so it has lot of bonding options. This makes possible the huge diversity of compounds that involve the element carbon, which in turn, makes possible the organic compounds that make life possible.
* Mild (low carbon) steel: approximately 0.05-0.15% carbon content for low carbon steel and 0.16-0.29% carbon content for mild steel (e.g. AISI 1018 steel). Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing. * Medium carbon steel: approximately 0.30-0.59% carbon content(e.g. AISI 1040 steel). Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components. * High carbon steel: approximately 0.6-0.99% carbon content. Very strong, used for springs and high-strength wires. * Ultra-high carbon steel: approximately 1.0-2.0% carbon content. Steels that can be tempered to great hardness. Used for special purposes like (non-industrial-purpose) knives, axles or punches. Most steels with more than 1.2% carbon content are made using powder metallurgy and usually fall in the category of high alloy carbon steels.
