Classification:
AWS A5.4 / ASME SFA5.4 E308-16
JIS Z3221 D308-16
Description :
Stainless Steel Welding Electrode E308-16 is a line titanium type welding electrode for extra-low carbon stainless steel.The weld metal has excellent mechanical properties and shows good resistance to intergranular corrosion due to the carbon content in it is ≤. 0.04% b. It can be used for all position welding with excellent performance:stable arc,small spatters,good appearance of weld.And also the welding electrode shows good heat-resistance character,not easy to turn red and gas porosity is not produced.
Application :
Welding of 18%Cr-8%Ni steel.
It is suitable for welding structures fabricated by extra-low carbon 022Cr-19Ni10 stainless steel,such as synthetic fibre,fertilizer,
petrochemical equipment, etc.

Notes on Usage:
1.Keep the arc as short as possible.
2.Remove dirts such as oil and dust from the groove.
3.Dry the electrodes at 350 (662 ) for 60 minutes before use
