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

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
