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.

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. Choose SJ101 now to unlock a new realm of efficient welding!

Submerged Arc Welding Flux AN-60 is a high-performance, agglomerated flux designed for efficient welding of carbon and low-alloy steels, such as Q345, 16Mn, Q390, and 15MnV. This neutral to active flux offers excellent slag detachability, smooth bead appearance, and superior weld metal integrity, making it ideal for automatic and semi-automatic submerged arc welding processes. Compatible with wires like EL12, EM12K, and Sv-08A, AN-60 ensures high deposition rates and minimal spatter, enhancing productivity in structural fabrication, shipbuilding, and pressure vessel manufacturing.
