SJ-501 submerged arc welding flux is an active aluminum-titanium type acidic sintered flux, designed for high-efficiency welding, providing stable arc combustion and excellent weld quality. The basicity index of this flux is approximately 0.5-0.8, suitable for welding low-carbon steel and low-alloy high-strength structural steel, and performs particularly well in the manufacturing of LPG (liquefied petroleum gas) cylinders. It ensures a fast welding speed (up to more than 70m/h), easy slag removal, low spatter, and enhances the mechanical strength and corrosion resistance of the weld, applicable to industrial applications such as ships, boilers, and pressure vessels.

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.
