EN ISO 17633-A : T 23 12 L P C1 2
Description：
E309LT1-1 is a stainless steel gas shielded flux-cored wire designed for welding of 22%Cr-12%Ni steel (SUS 309S), 18% Cr-8%Ni clad steel and dissimilar materials such as Cr-Mo steel or mild steel to stainless and build-up welding of carbon steel. It provides excellent usability with stable arc, less spattering, good bead appearance. The weld deposit has good crack and high temperature resistance. Used on 22%Cr-12%Ni steel (SUS 309S), 18% Cr-8%Ni clad steel and dissimilar materials welding.
