Sale! Hyundai Low-Hydrogen Welding Electrode 2.6mm 5kg Pack | S-8018.B2
$33.60 $42.00
The Hyundai S-8018.B2 is a premium iron powder, low-hydrogen welding electrode developed for welding 1.25% Cr-0.5% Mo heat-resistant steels. These steels are commonly used in boiler pipes, power plants, oil refining equipment, and high-temperature chemical processing.
This electrode features low hydrogen content, which minimizes the risk of hydrogen-induced cracking, ensuring weld integrity. It has high deposition efficiency due to the iron powder coating, making it ideal for thick-section welding and repair welding of cast steel components.
With stable arc performance, excellent mechanical properties, and easy slag removal, the Hyundai S-8018.B2 is a reliable choice for high-temperature applications requiring post-weld heat treatment (PWHT).
