The Professional's Choice for Dissimilar & High-Corrosion Stainless Welding

When your project demands exceptional corrosion resistance and the ability to join dissimilar metals, BLUME® E309LMo Flux Cored Wire delivers unmatched performance. Specially formulated with molybdenum (Mo) for improved resistance to aggressive environments, this wire is ideal for high-strength, all-position welding where stainless steel meets carbon steel, or where superior corrosion protection is needed.

BLUME® E309LMo offers smooth arc characteristics, minimal spatter, and an excellent bead appearance, making it the perfect choice for fabricators who need speed, reliability, and weld integrity in every joint.

Why BLUME® E309LMo Outperforms Ordinary Stainless Steel Flux Cored Wire?

Key Features

✔ Molybdenum-enhanced: Superior corrosion, pitting, and oxidation resistance

FAQ

Q: What is the main advantage of BLUME® E309LMo over E309L?
A: The added molybdenum (Mo) significantly improves corrosion and pitting resistance, especially for chemical and marine applications.

Q: Can I use BLUME® E309LMo for stainless-to-carbon steel welding?
A: Yes! It is specifically designed for dissimilar metal joining with superior crack and corrosion resistance.

Q: What shielding gas should I use?
A: Recommended gases include 100% CO₂ or CO₂/Argon mixtures for best weld quality.

Q: Is BLUME® E309LMo suitable for out-of-position welding?
A: Absolutely! This wire is rated for full all-position welding including vertical and overhead.
