IDENTIFICATION
Griduct 95B 92, EE 9015-B92
CLASSIFICATION
AWS / SFA 5.5: E 9015-B92
DESCRIPTION
Non-synthetic Hydrogen controlled, heavy coated basic type electrode depositing 9Cr-0.2Mo-16W-0.2V- Nb alloyed weld metal.
Deposited weld metal has improved creep strength toughness and fatigue life and oxidation and corrosion resistance at elevated temperature upto 620°C.
