Dear welding colleagues, what type of submerged arc welding wire and flux should be used for welding Q460?
Q460D, low-alloy high-strength steel plate. Execution standard: GB/T 3274-2007 – Chemical composition standards for hot-rolled thick plates and strips of carbon structural steel and low-alloy structural steel. Standard for chemical composition: GB/T 1591-2008 – Low-alloy high-strength structural steel Q460D, low-alloy high-strength plates. Its steel grade is prefixed with “Q”, which denotes the yield strength of the steel; the number that follows indicates the value of the yield strength, in MPa. For example, Q460 means that the yield strength is 460 MPa. D is a -20-degree impact.
Grade Q460 has the highest strength; it exhibits excellent overall mechanical properties in the normalized, normalized and tempered, or quenched and tempered states. Deoxidization is achieved entirely through the use of aluminum, and it comes in quality grades C, D, and E, making it a suitable steel grade that ensures good toughness. Used for various large-scale engineering structures as well as lightweight structures that require high strength and can handle heavy loads.
