CLASSIFICATION
AWS A 5.5 E8018-B6L
DIN 8575-84 ECrMo5BL20+ BS 2493-85 E5Cr MoBL

DESCRIPTION
A basic coated low hydrogen electrode depositing extra low carbon 5% Cr / 0.5% Mo weld metal. It is intended for welding creep-resisting steel of matching composition used widely in chemical and petrochemical plants because of excellent resistance to hydrogen attack and corrosion by high sulphur crude oils at service temperature upto 650°C. The weld deposit meets X-ray / Radiographic quality code requirements.
