DETAILS

PRIMALLOY® JMS®-309LSi is a premium stainless steel MIG wire designed for welding 309 and 309L stainless steels as well as dissimilar joins between stainless steel and carbon steel. The increased Silicon (Si) promotes excellent weld pool fluidity resulting in smooth bead appearance, improved wetting and less post-weld cleanup. PRIMALLOY® JMS®-309LSi delivers consistent arc stability, low spatter levels and consistent, high-quality finishes.

Features

  • Excellent weldability – Stable arc, low spatter, good wetting and fluidity brings outstanding bead appearance
  • Superb feedability – Unique manufacturing technology results in an even clean wire surface, stable wire feeding and low contact tip abrasion
  • Excellent weldability
  • Superior feeding and arc stability

Typical Applications

  • For welding UNS 309 and 309L austenitic grades S30900 and S30908
  • Ideal for welding carbon steels to stainless steels
  • As a buffer layer in many hardfacing applications
  • Power Generation Construction
  • For dissimilar joints weld between CrNi or CrNiMo stainless steel to mild steel or low alloy steel

Welding Positions

  • All positions

Shielding Gas

  • Ar/(1-5%)CO2 | Ar/(1-2%)O2
