High Carbon steels SAW welding wire F7A/P4-ECG and welding flux welding makings
Used for -40C impact required environment, generally used for heat treatment under the occasion of pressure vessels, pipelines and other welding.
What are the characieristics?
●The metal powder core submerged arc welding wire of 480MPa grade high strength steel is welded with GXL-121 flux. The arc combustion is stable, the slag removal is easy, and the welding pass forming is beautiful.
●The weld metal has excellent mechanical properties, low content of P and S, and excellent low temperature impact performance.
