flux cored STAINLESS STEEL welding wire e309LT1-1

The E309LT1-1 is a flux-cored，gas-shielded stainless steel wire designed for all-position welding of dissimilar steels, stainless-to-carbon steels, and cladding applications. With the flux system, it provides excellent weldability by delivering a stable arc, low spatter, and smooth bead appearance. The deposited weld metal contains a balanced ferrite content, ensuring resistance to hot cracking and solidification defects.
