Main components of steel plate

The main components of steel plate are iron and carbon. Iron is the most important element in steel plates, accounting for more than 99% of the total composition of steel plates. It provides hardness, strength and toughness to steel plates. Carbon is a key element that affects the performance of steel plates. Its content is usually between 0.08% and 2.0%. An increase in carbon content will increase the hardness and strength of the steel plate, but it will also reduce its toughness and weldability.

In addition to iron and carbon, steel plates contain a number of other elements, including:

Manganese: Improves the strength and hardness of steel plates, while also helping to improve corrosion resistance and weldability.
Silicon: Improves the wear resistance and hardness of steel plates, but may reduce its corrosion resistance.
Phosphorus and Sulfur: often considered hazardous elements as they can negatively impact the mechanical and corrosion properties of steel plates.

In addition, alloy elements such as chromium, copper, and nickel may also be added to the steel plate. These elements can improve the corrosion resistance and high-temperature strength of the steel plate. They are often used to manufacture steel plates in fields such as impact resistance, wear resistance, marine engineering, and nuclear engineering.
