309LT1-1 Dynacore® stainless steel flux-cored (FCAW-S) welding wire is used to join dissimilar steels and materials of AISI 309 composition. It is also recommended for use as a first layer in a single or multilayer surfacing of non-alloy and low ally steels to give a 304L deposit. By specifying low carbon content in this alloy, it’s impossible to obtain resistance to intergranular corrosion due to carbide precipitation without the use of stabilizers such as columbium or titanium. This material is generally used with 100% carbon dioxide, or mixtures of argon/carbon dioxide, typically a 75%/25% mixture. Recommended 5/8 in .- 3/4 in. wire stick out. Conforms to AWS A5.22.
