SJ301 submerged arc welding flux is a high-performance agglomerated calcium-silicate flux designed for efficient welding of low-carbon and low-alloy steels. With a neutral basicity index of 1.0, it delivers stable arc performance, effortless slag detachment, and superior weld bead aesthetics, making it ideal for high-speed applications in industries like pipeline construction, bridge building, and machinery fabrication. Certified under AWS A5.17 F6A0-EL8 and F7A2-EM12K standards, this flux minimizes porosity and ensures strong mechanical properties, such as tensile strength up to 670 MPa when paired with EM12K wire. As a reliable choice from Chinese manufacturers, SJ301 enhances productivity by supporting AC/DC currents and multi-layer welding without interface defects. Perfect for structural projects requiring durability and cost-efficiency.
