CHE58-1 is a marine-grade non-alloy electrode with basic-iron powder coating, suitable for all-position AC/DC welding. Its proprietary black coating delivers:

• Superior arc stiffness & minimal arc blow

• Refined bead appearance with low spatter

• Easy slag removal

• ≈110% deposition efficiency

• Consistent low-temp toughness & crack resistance

• Nuclear-certified by multiple power plants

Applications: Critical structures including:

• Marine steels: Grades A/B/D/E, AH36/DH36/EH36 (ABS/LR/DNV... compliant)

• Pressure equipment: Boilers, vessels

• Offshore drilling platforms
