CHE507 is a basic-coated non-alloy steel electrode for all-position DC+ welding. Delivers firm arc force (minimizes arc blow) with refined bead appearance, low spatter, easy slag removal, and exceptional stability. Deposited metal offers stable low-temp toughness, superior ductility, and crack resistance. Designated for National Welder Competitions.

Applications: Critical structures including:

• Ship components (marine grades A/B/D/E)

• Boilers & pressure vessels

• Pipelines

• Carbon/low-alloy steels (e.g., Q355)
