What is AWS Class E309LT1-1/T1-4 Flux Core?
AWS Class E309LT1-1/T1-4 Flux Core welding wire is designed for joining dissimilar steels and providing excellent corrosion resistance. Its typical chemical composition includes 23–25% Cr, 12–14% Ni, 0.08% C max, and trace amounts of Mn, Si, P, and S. Mechanical properties feature a tensile strength of 620–750 MPa, yield strength around 450 MPa, and elongation of 30–35%, ensuring ductile, crack-resistant welds. The wire offers stable arc performance, minimal spatter, and strong slag detachability, making it ideal for stainless steel overlays, dissimilar joints, and applications requiring high corrosion resistance and structural integrity.
