Griduct 88C3 , E 8018-C3

CLASSIFICATION
AWS/SFA 5.5 E8018-C3 BS 2493 1NiBH,
DIN 8529 EY46551NiB

DESCRIPTION
A basic coated low-hydrogen electrode producing a nominal 1.0% Ni weld metal, designed for welding C-Mn steel and low alloy steel where excellent fracture toughness at temperature down to -60°C is required. The addition of 1.0% Ni produces microstructural refinement, with improved tolerance to procedural variations compared to plan C-Mn weld metal.  The deposited weld metal is of X-ray quality.
