Description:
CHT711 is a rutile
type flux cored wire applicable for all-position welding by CO2 gas
shielding. It shows excellent welding performance and higher efficiency in
welding. Vertical down welding could be processed. It is widely used in
structures fabricated by mild steel and 500Mpa grade high tensile steel,
such as ships, pressure vessels, machineries, bridges, etc.
