SelectAlloy 307EU-C
Stainless Steel / Metal Cored / Gas Shielded
Features
- Increased Si content compared to grades of similar alloy composition improves bead wetting and arc stability.
- Metal cored benefits include the ability to successfully bridge gaps when part fit up is not as designed, higher travel speeds with subsequent lower heat inputs at equal amperages, and ability to join thin materials.
- Applications for this alloy type 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 in 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.
