In steel  besides Carbon (C) (and of course Iron (F)!), polluters, we can also observe the occurrence of  alloy elements which improve the properties of the steel. These are the reasons why alloy steels are better than a pure alloy of iron with carbon. The first group consists of admixtures...

Banally, pollution plays a very important role right after coal. WHY? Because if there is too much of it, even adding the entire Mendeleyev table will not make the steel suitable for making knives out of it. Polluters in steel are Sulphur (S), Phosphorus (P), Hydrogen (H), Oxygen (O), Nitrogen...

The material which is most commonly used in the manufacture of knives is steel. Below I present  the first part of a brief description of steel. Steel is an alloy of iron (Fe) with carbon (C) and other elements. Carbon is the main alloy element in steel. Iron + Carbon. That could easily be...
