A5.17 F7A2–EM12K
PRODUCT DESCRIPTION
SF-300 is a semi-basic agglomerated flux for welding of structural steel in combination with appropriate SAW wire such as SW-12M (AWS A5.17 EM12K). Weld bead hardly increases Si and Mn. It belongs to metallurgy neutral. It has perfect welding performance, stable arc, good surface, excellent slag detachability, high impact toughness at low temperature.
APPLICATIONS AND MATERIALS TO BE WELDED
SF-300 is designed for general steel structure, boilers, pressure vessels, pipeline and low alloy steel structure.
