Griduct 86C3, E 8016-C3
CLASSIFICATION
AWS/SFA 5.5: E8016-C3 BS 2493 1NiBH DIN 8529
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.
