Select ER307

Stainless Steel / Solid / Gas Shielded

Resources

Features

  • Increased silicon (Si) content compared to grades of similar alloy composition improves bead wetting and arc stability.
  • Unique manufacturing techniques provide enhanced arc stability and stable feeding.
  • Applications include welding dissimilar steels such as austenitic manganese steel and carbon steel forgings or castings where moderate-strength welds with good crack resistance is needed.
  • Also used for welding automotive exhaust systems for joining mismatched material combinations of austenitic stainless steel, carbon steels, and ferritic stainless steels along with armor plate material applications.
