IDENTIFICATION
Griduct 85B6L, E 8015-B6L

CLASSIFICATION
AWS/SFA 5.5: E 8015-B6L

DESCRIPTION
Hydrogen controlled, heavy coated, basic type electrode depositing extra low carbon 4.0% Cr / 0.50 Mo weld metal. It is intended for welding creep resisting steels of similar composition used in steam generation plant operating at temperature up to 600°C. The weld deposit meets x-ray / radiographic quality requirements.
