Carbon (C):
Content range: 0.15%~0.18%
Function: Carbon is one of the most important elements in steel and has a significant effect on the strength and hardness of steel. In AH36, the carbon content is precisely controlled to ensure that the steel plate has sufficient strength and hardness while maintaining good welding performance.
Silicon (Si):
Content range: 0.15%~0.50%
Function: The addition of silicon helps to improve the corrosion resistance and wear resistance of the steel plate. In AH36, the appropriate amount of silicon content makes the steel plate have better durability in harsh environments such as the ocean.
Manganese (Mn):
Content range: 1.20%~1.45%
Function: Manganese is an important alloying element in steel and plays a key role in the strength and toughness of steel. In AH36, the high content of manganese helps to improve the overall mechanical properties of the steel plate.
Phosphorus (P) and Sulfur (S):
Content control: The content of phosphorus and sulfur is strictly controlled at extremely low levels (such as phosphorus ≤ 0.025%, sulfur ≤ 0.015%) to ensure the purity and performance stability of the steel plate. These two elements are generally regarded as harmful impurities in steel because they may reduce the mechanical properties and welding properties of the steel.
Other elements:
In addition to the above main elements, AH36 may also contain trace amounts of other alloying elements, such as niobium (Nb). The addition of these elements can further improve the properties of the steel plate, such as improving strength, toughness or corrosion resistance. However, the content of these elements is usually low, and their specific effects may vary depending on the steel plant and production process.
