Features and Applications
- Applicability in submerged arc welding of steel materials with medium or high levels of tensile strength
- Usability in manufacture processes of pressure vessels, boilers, pipes, ship and other steel construction purposes
- Decreased affinity to Oxygen due to high content of Silicon
- lncreased electric conductivity, and increased resistance to corrosion due to copper coating
