BLUE MAX® MIG 309LSi is designed for joining stainless steel to mild or low alloy steel. The same composition as Blue Max® MIG 309L with higher silicon content to improve the bead appearance and increase welding ease.
AWS / Classification: AWS ER309Si, ER309LSi

Overview

BLUE MAX 309L 0.045 inch welding wire is 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
  • Q2 Lot® - Certified Material Test Report showing actual wire composition, Country of Origin and calculated ferrite number (FN) of each lot is available online in the Certificate Center
  • Proprietary surface lubricant for steady feeding and arc stability leading to exceptional performance at high wire feed speeds
  • High silicon level for increased puddle fluidity and toe wetting
  • Controlled ferrite content for maximum corrosion resistance
  • 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

  • 98% Argon / Balance O2
  • 90% He / 7.5% Argon / 2.5% CO2
