The chemical composition of Q460ND mainly includes iron, carbon, silicon, manganese, phosphorus, sulfur, chromium, nickel and other elements. Among them, carbon is the main element affecting the strength and hardness of steel, silicon and manganese elements can improve the strength and hardness of steel, while phosphorus and sulfur elements can increase the toughness of steel. Alloying elements such as chromium and nickel, on the other hand, can improve the corrosion resistance of steel.
The mechanical properties of Q460ND mainly include tensile strength, yield strength, elongation and section shrinkage and other indicators. Among them, tensile strength is an important indicator to reflect the strength of steel, yield strength represents the maximum bearing capacity of steel in the force. Elongation and section shrinkage reflect the plastic properties of steel.
The tensile strength of Q460ND ranges from 460-540 MPa and the yield strength ranges from 345-420 MPa. In addition, Q460ND has good impact toughness and low-temperature toughness, and can maintain excellent mechanical properties at lower temperatures.
Q460ND has good welding performance and can be welded using a variety of welding methods. Its welded joints have good strength and toughness, and can meet the requirements of structural safety. In addition, Q460ND also has good weldability and can adapt to the requirements of various welding processes.
