Constituents of Steel

Steel is an alloy made primarily of iron, with varying amounts of carbon and other elements added to achieve specific properties. The exact constituents of steel can vary depending on the type and grade of steel being produced. The following are some of the most common constituents of steel:

Iron: Iron is the primary constituent of steel, typically making up over 90% of the material.

Carbon: Carbon is added to steel in varying amounts, typically between 0.2% and 2%, to achieve specific properties such as hardness and strength.

Manganese: Manganese is often added to steel to improve its strength, toughness, and workability.

Chromium: Chromium is added to steel to improve its resistance to corrosion and oxidation.

Nickel: Nickel is added to steel to improve its resistance to corrosion and to increase its strength at high temperatures.

Molybdenum: Molybdenum is added to steel to improve its strength, toughness, and resistance to corrosion and high temperatures.

Vanadium: Vanadium is added to steel to improve its strength, toughness, and resistance to fatigue and wear.

Silicon: Silicon is added to steel to improve its strength and resistance to corrosion and oxidation.
