GM 308L Si

IDENTIFICATION
GM 308LSi, ER 308LSi

CLASSIFICATION
AWS/SFA 5.9 ER308LSi

DESCRIPTION
A solid, smooth wire primarily intended for welding the low carbon, 18% Cr, 10% Ni, type 304, austenitic stainless steels. Deposited weld metal has improved resistance to general corrosion. The deposited weld metal is of radiographic quality.
