DESCRIPTION:
WELDMETAL – E-308L is a Rutile type stainless steel electrodes suitable for welding of AISI 301,302,304 & 308 grade stainless
steel, its specially design to yield a weld deposit of extra low carbon and 18Cr-8Ni grade stainless steel. the weld metal is highly
resistant to cracks, corrosion and scaling at high temperature up to 800*C. Easily and equally operates well on AC or DC(+) in all
conventional position. It is easily striking /re-striking, with very little spatter, easily removal of slag with excellent bead appearance
with radiographic quality weld.
APPLICATIONS:
WELDMETAL- E308L suitable for welding of AISI grades steel such as 301L, 302L,304L, 308L, Normal carbon grades steel like 302,
304 & 308 and welding of Clad steels of similar composition, it is also overlays and surfacing applications and also in un-alloys, &
low alloy steels. It is specially recommended for extra low carbon stainless steel.

RECOMMENDATIONS:
Re-dry the electrodes at 200*C for one hour, use low current, short arc, and stringer bead technique. maintain inter pass
temperature 150*C max. Use a stainless steel wire brush for cleaning the weld. Use directly from the oven, store the electrodes in Dry Place.
