Facilitating vertical up and overhead welding, SelectAlloy 308L-AP offers smooth arc transfer, quick freezing slag, and minimal convexity. Model 309L-AP delivers optimal puddle control, slag freezing, slag release, and bead shape. Model 316L-AP provides resistance to intergranular corrosion due to carbide precipitation without adding stabilizers; molybdenum provides creep resistance at elevated temperatures and resistance to pitting in halide environments.
