IDENTIFICATION
Griduct 100, E 8018-G
CLASSIFICATION
AWS/SFA 5.5: E8018G
DESCRIPTION
Basic coated, hydrogen controlled, iron powder electrode depositing weld metal containing about 1.2% Mn and 2.1% Ni.The electrode is specially recommended for welding thick sections of fine grained, high tensile low temperature steels. The weld metal gives excellent impact strength down to minus 50°C. Deposited welds are of radiographic quality. Weld deposit is of extremely high metallurgical purity & very low hydrogen content.
