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.

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.
