GRNOX 308LT E 308L-16
CLASSIFICATION
AWS/SFA 5.4 E308L-16; IS: 5206: E 19.9.LR26
DESCRIPTION
A rutile coated stainless steel electrode with a controlled composition and low ferrite content, designed for cryogenic service requiring>0.38 mm charpy lateral expansion at minus 196°C. The electrode has excellent arc stability and low spatter loss. The electrode can be manipulated easily in all welding positions. The deposited welds are of radiographic quality.
