S-Weld 309L Stainless Steel Welding Electrode

Notes on Usage:

  • Keep dry. If damp, dry the electrodes at 150C for 30 minutes before use.
  • For X-ray quality level, dry at 250C for 30 minutes.
  • Use small current and keep the arc as short as possible.

Description

S-Weld SS309L-16 is a titania type electrode. The 22%Cr-12%Ni alloy in the weld metal makes austenite structure which contains suitable quantity of ferrite. Heat resistibility and corrosion resistibility are good at high temperature for welding of dissimlar metals, hardening alloy steel, low carbon clad steel, SUS 309S and 13Cr steels.
