ZT · SJ605 (Fluoro-alkali type)

· Description: SJ605 is a fluorine-based high-basicity sintered flux with a particle size of 2.0-0.45mm (10-40 mesh). The flux is metallurgical neutral, has good welding processability, stable arc, easy slag removal, beautiful weld formation, high purity of weld metal and high low temperature impact toughness.

· Application: It can weld fine grain low temperature steel and high strength structural steel with appropriate welding wire, such as low temperature pressure vessels, oil storage tanks and oil and gas pipelines, marine engineering, nuclear industry, etc.

· The test results of SJ605 matching different welding wires are listed below:
