MORE INFORMATION:

carbon (С)

Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.
Chromium (Сr)

Chromium affects the hardenability of steel, gives the alloy anti-corrosion properties and increases its wear resistance. It is found in all grades of stainless steel.
Manganese (Mn)

Manganese is used in the steelmaking stage. It is able to increase the hardness of steel. Steels with significant manganese content are used to make various strong things - rails, safes and so on.
Molybdenum (Мо)

It is used for specialty and high-speed steels. Molybdenum is a hard-alloying element, it prevents brittleness and brittleness of the blade, giving it the necessary rigidity, making it sufficiently resistant to high temperatures.
Silicon (Si)

Silicon increases the strength and wear resistance of steel. Like manganese, it makes steel more stable and reliable.
Nickel (Ni)

Nickel increases the corrosion resistance of steel and can slightly increase strength.
sulfur (S)

Sulfur, like phosphorus, is one of the harmful technological impurities in steels and alloys. Increase of sulfur content significantly reduces mechanical and physicochemical properties of steels, in particular, ductility, impact toughness, abrasion resistance and corrosion resistance. The limits of sulfur content as a technological impurity are 0.035...0.06%.
Phosphorus (P)

Phosphorus is one of the harmful technological impurities in steels and alloys. An increase in its content, even by a fraction of a percent, while increasing strength, simultaneously increases brittleness. The harmful effect of phosphorus is especially strong at higher carbon content. The limits of phosphorus content as a technological impurity are 0.025...0.045%.
Vanadium (V)

It is used in the production of special grades of steel, including tool steel. It is responsible for elasticity and enhances the properties of chromium, makes the metal inert to aggressive chemical media.
