GUJIN® is a kind of low manganese low Submerged Arc Welding Wire Aws El8. It is matched with high manganese and high silicon type fluxes. Insensitive to rust on the base metal, excellent bead forming and slag separation. It is the most commonly used submerged arc welding wire. Monoles or dipoles. Can be used for AC/DC.

Submerged Arc Welding Flux SJ-501 A is a high-performance agglomerated aluminum-rutile type acid sintered flux with a basicity index of approximately 0.5-0.93 and a particle size of 10-60 mesh (about 0.3-2.0mm). It is specially designed for low-alloy steels and high-strength steels (such as ASTM A514, A517), supporting single-wire or multi-wire high-speed welding (up to 100m/h), and is suitable for applications such as small cylinders, LPG tanks, pressure vessels, and shipbuilding. This flux complies with the standards of EN760 SA AR 1 88 AC H5 and AWS A5.17/5.23 F7A0-EL12, providing stable arc, excellent slag detachability, smooth weld seams, and resistance to cracks and pores. It is not sensitive to surface rust and scale, ensuring efficient welding quality and excellent mechanical properties, such as high impact toughness and tensile strength.

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.

SJ101 is an advanced fluorine-alkaline type sintered flux, specifically designed for submerged arc welding processes, offering an excellent welding experience. Whether for single-layer or multi-layer welding, it ensures a stable arc, easy slag removal, and smooth weld formation. It is particularly suitable for carbon steel and low-alloy steel structural components, such as oil storage tanks and bridge components. The low-impurity formula reduces weld defects, enhances impact resistance and mechanical properties, and supports AC/DC current operation with uniform particle size (10-60 mesh). Unlike traditional fluxes, SJ101 has optimized alkalinity (approximately 1.8), reducing spatter and improving production efficiency. GJFlux is committed to high-quality welding materials, ensuring that SJ101 meets international standards (such as AWS), helping you reduce costs and enhance project reliability.
