1kg – E309LT0-3 1.0mm Stainless Steel Flux-Cored MIG Wire for Dissimilar & Clad Steel Welding
Product Overview:
• E309LT0-3 stainless steel flux-cored wire for welding dissimilar steels and stainless-to-carbon steel joints
• Low carbon formulation reduces carbide precipitation and intergranular corrosion
• Ideal for welding clad steels, buffer layers, and transition joints
• Self-shielded or gas-shielded depending on application; typically used with 100% CO₂ or 75% Ar / 25% CO₂
• Excellent crack resistance and bead appearance in all-position welding
Technical Specifications:

Chemical Composition (Typical Values):
• Carbon (C): ≤ 0.04% – Low carbon for corrosion resistance
• Chromium (Cr): 22.0–24.0% – High corrosion and oxidation resistance
• Nickel (Ni): 12.0–14.0% – Enhances ductility and toughness
• Manganese (Mn): ~1.0–2.5% – Supports arc stability and weld pool control
• Silicon (Si): ~0.90% – Aids slag formation and bead appearance
• Molybdenum (Mo): ≤ 0.75% – Optional trace for added corrosion resistance
• Phosphorus (P): ≤ 0.04% – Controlled to prevent embrittlement
• Sulfur (S): ≤ 0.03% – Controlled to prevent hot cracking
• Copper (Cu): ≤ 0.75% – May improve corrosion resistance
• Iron (Fe): Balance – Forms the matrix of the weld deposit
