DETAILS

BLUE MAX® MIG 309L ideal for joining stainless steels to themselves or to carbon or low alloy steels, and can be used at temperatures of up to 700°F (371°C) Reduced carbon levels (0.03% max) offer increased resistance to inter-granular corrosion

Features

  • High silicon level for increased puddle fluidity and toe wetting
  • Proprietary surface lubricant for steady feeding and arc stability
  • Controlled ferrite content for maximum corrosion resistance
  • The same composition as Blue Max® MIG 309L with higher silicon content to improve the bead appearance and increase welding ease
  • Excellent contour of the weld minimizes the need for grinding
  • Q2 Lot® - Certificate showing actual wire composition and calculated ferrite number (FN) available online

Typical Applications

  • Designed for joining stainless steel to mild or low alloy steel
  • Performs exceptionally at high wire feed speeds

Welding Positions

  • All

Shielding Gas

  • Short Circuiting Transfer: 90% Helium / 7.5% Argon / 2.5% CO2, Axial Spray Transfer: 98% Argon/ 2% Oxygen
