DEFINITION OF STEELS EFFECTS OF ELEMENTS ON STEEL

(Sİ) SILICON

Removes oxides in steelmaking. It is the element found in all steels. Flexibility increases strength and hardness.
Generally, it is between 0.15%~2% in steel.

(C) CARBON

It is the element with the main hardening effect in steel.
Any increase in carbon content increases the hardness and tensile strength of the steel in the hot or normalized state.
However, its flexibility weakens its ability to be hammered, welded and cut.

(Mn) MANGANESE

Improves the resistance of the steel, increases the quenching depth, increases the resistance to rusting (corrosion).
The property that increases the hardness and resistance depends on the amount of carbon. In addition, it weakens its flexibility slightly.

(P) PHOSPHORUS

The effect on steel is not good, but harmful. That's why it doesn't want to be.
Unwanted phosphorus should be more than 0.40%.

(S) SULFUR

It causes the steel to become brittle and brittle.
It is desirable that it should not be like phosphorus.
However, this feature is eliminated by the addition of manganese in free cutting steels.
The ratio in steel is as much as phosphorus.

(Cr) CHROMIUM

It increases the heat resistance, strength and hardening properties of steel.
It increases the resistance against rusting and corrosion as well as abrasion.
The ratio in steel is between 0.80%~12.5%.
In stainless steels, it is 3.5%~22%

(Ni) NICKEL

One day with chrome allows the hardening to go down to its depth close to the core.
Chrome nickel steels are rustproof and heat resistant.
It is between 0.40~5.1% in the special steels formed.

(Mo) MOLYBDENUM

It increases the tensile strength of steel, especially with its heat resistance, and its ability to be welded.
Molybdenum in alloy steels; When used with chromium nickel, it increases the yield and tensile strength values.

(V) VANADIUM

Improves steel's resistance to heat. It keeps the steel blades sharp longer.
Increases tensile strength and yield limit values.

(W) WOLFRAM

Increases the resistance of steel. In tool steels, cutting edge hardness provides increased service life and high temperature resistance.
Wolfram has a strong tendency to form carbide and is preferred in the production of heat resistant steel, as it is ensured that the steel does not lose its hardness by tempering at high operating temperature.
