It is a kind of gas-shielded flux-cored welding wire for low-carbon steel and 490MPa high strength steel. FRN-YT500T-5
is a kind of calcium oxide-calcium fluoride type CO2 gas-shielded flux-cored welding wire. It has excellent welding performance, stable arc, good slag detachability, beautiful appearance of weld and high welding efficiency. Suitable for downhand welding and flat fillet welding. Weave bead welding can be applied to improve productivity. The weld metal has been given toughening treatment by microelements, so it has excellent low temperature toughness above -30℃ and good crack-resistance.
Used for welding carbon steel and low-alloy structural steel with tensile strength higher than or equal to 490MPa. Used for welding some key structures like shipbuilding, vehicles, mechanical manufacture, pressure vessels, petrochemical machinery, hoisting machinery, etc.
