- C Carbon forms carbides of all other elements by the hardness procedure. The carbides of the different elements are different hardnesses.
- CR Chrome causes a certain rust inertia and increases the hardness of the blade.
- Mn Manganese binds redundant oxygen and degasses the melt. Hardness does not increase proportionately to higher alloy mixtures.
- Mo Molybdenum has the hardest carbide. It increases firmness and corrosion resistance. With higher alloy portions the heatproof quality increases.
- P Phosphorus is unwanted. It increases the hardness, however it makes the steel fragile with higher alloy portions.
- SI Silicon degasses the melt. With small amounts, tensil strength improves.
- S Sulfur is an unwanted element. It is regarded as pollution and is often not mentioned with the analyses.
- V Vanadium improves hardness & breaking strength. It contributes to finer grain formation.
