GRIDUCT 200

IDENTIFICATION
Griduct 200, E 9018-G

CLASSIFICATION
AWS/SFA 5.5 : E9018G

DESCRIPTION
Basic coated, hydrogen controlled, iron powder electrode depositing weld metal containing about 1.4% Mn and 2.0% 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.
