* American term

C	Carbon forms carbides of all other elements during the hardening process. The carbides of the different elements have different levels of hardness.
Cr	Chromium provides a certain resistance to rust and simultaneously increases hardness and toughness.
Mn	Manganese binds excess oxygen and degasses the melt. At the same time, it increases hardness and toughness, provided the alloying element content is not too high.
Mon	Molybdenum is the hardest carbide. It increases strength, toughness, and corrosion resistance. Higher alloying proportions also increase heat resistance.
P	Phosphorus is undesirable. While it increases hardness, it makes steel brittle at higher alloying levels.
Si	Silicon degasses the melt. In small amounts, it improves tensile and compressive strength.
S	Sulfur is an undesirable element. It is considered an impurity and is often not mentioned in analyses.
V	Vanadium primarily improves toughness and fracture strength. It also contributes to finer grain formation.
