S-309L.16
COVERED ELECTRODES FOR STAINLESS STEELS
AWS A5.4 / ASME SFA5.4 E309L-16
JIS Z3221 D309L-16
l Applications
Welding of 22%Cr-12%Ni steel. Welding of dissimilar metals and build-up welding of stainless steel on carbon steel or low alloy steel.
l Characteristics on Usage
S-309L.16 is a lime-titania type electrode and its usability is excellent.
As the all-weld metal contains extra low caron and high quantity of delta ferrite, its corrosion and heat resistibility are also good.
l Notes on Usage
a) Dry the electrodes at 350℃ (662℉) for 60 minutes before use.
b) In case of clad steel welding, pay attention to the degree of penetration into base plate.
c) Keep the arc as short as possible.
