A517Gr steel plate Detailed introduction
All A517Gr series steel plates have high strength, good toughness and low crack sensitivity.
They are often used to manufacture equipment or components that require high material properties, such as pressure vessels, boilers, offshore platforms, ships, etc.
Chemical composition content of A517Gr steel plate:
Carbon (C) : 0.10-0.20%. Carbon is the main alloying element in steel and has a significant effect on the strength and hardness of steel. The right amount of carbon content can improve the strength and hardness of steel, but too high will lead to increased brittleness of steel.
Manganese (Mn) : 0.60-1.00%. Manganese in steel as a deoxidizer and desulfurizer, can improve the strength and hardness of steel, improve the cold working performance of steel, and help to improve the hardenability of steel.
Phosphorus (P) : ≤0.035%. Phosphorus is generally regarded as a harmful element in steel because it reduces the ductility and toughness of steel and increases the cold brittleness of steel. Therefore, it is necessary to strictly control the content of phosphorus in the production process of steel.
Sulfur (S) : ≤0.035%. Sulfur is also a harmful element, which will cause the hot brittleness of steel during hot processing, reducing the mechanical properties and weldability of steel.
Silicon (Si) : 0.15-0.35%. Silicon mainly plays a deoxidation role in steel, which can significantly improve the strength and hardness of steel, but also reduce the plasticity and toughness of steel.
