Golden Bridge E70T-5C (JQ-YJ507-1) Flux-Cored Welding Wire
SKU:JQ-YJ507-1-045-0011
JQ-YJ507-1
JQ YJ507-1 is a calcium oxide-fluoride basic CO2 gas shielded flux-cored welding wire, which has good welding performance, effortless slag removal ability and optimal bead appearance. The product is applicable for flat welding and flat angle welding. The deposited metal is toughened by trace elements, which has excellent low-temperature toughness and good crack resistance.
The product is applicable for welding structural steel with tensile strength of 490MPa, and commonly used in the fields such as ships, bridges, construction machinery, pressure vessels, marine engineering, coal mining machinery, construction machinery, etc. It is mainly used for welding in important positions.
