USA 80S-D2 is designed to give high strength weld son high sulfur bearing (free-machining) steels or medium carbon steels. This wire contains additional amounts of manganese and silicon which, when alloyed with 0.50% molybdenum, produces weld deposits which have high ductility, excellent impact values and tensile strengths of approximately 100,000 psi. USA 80S-D2 is commonly used on low carbon and low alloy steels such as AISI 4130 where tensile strengths provided by plain carbon steel wires are inadequate. A well balanced silicon content gives this wire superior arc stability, a low spatter level and a flat bead with excellent appearance. USA 80S-D2 produces X-ray quality, porosity free welds even over dirt, rust or mill scale.
36" Cut lengths are packaged in 1lb. tubes to provide you the flexibility of buying only what you need for your job.
High quality rods, makes very strong TIG welds, can also be used for gas welding.
I hate to admit it but I bought this to use for pattern making of tubing projects. Its nice and straight and bends easily of course. As far as tig welding I have no idea how well it works.
