High Carbon steels SAW welding wire F7A/P6-ECG and welding flux weld fabrication stuff
Used for -50C impact required environment, generally used for shipbuilding, pipeline, pressure vessel welding.
What are the characieristics?
●Metal powder core submerged arc welding wire for 480MPa grade high strength steel; With GXL-121 flux welding, welding arc combustion is stable, easy to remove slag, welding pass forming beautiful.
●The weld metal has excellent mechanical properties, low content of P and S, and excellent low temperature impact performance.
