PRODUCT DETAILS
Q355 carbon steel plate is a low alloy high-strength structural steel, which belongs to the carbon steel plate material under Chinese national standards. It has good comprehensive performance, such as high strength, high toughness, good welding performance and processing performance.
Q355 carbon steel plates are divided into five grades based on their yield strength and tensile strength: Q355A, Q355B, Q355C, Q355D, and Q355E. Q355 carbon steel plates of different grades have different mechanical properties and chemical compositions.
The chemical composition of Q355 carbon steel plate mainly includes elements such as carbon, silicon, manganese, phosphorus, and sulfur. Among them, carbon is the main element affecting the performance of steel, while silicon and manganese can improve the strength and toughness of steel. Phosphorus and sulfur have a negative impact on the properties of steel.
