1kg – E312 0.8mm Stainless Steel MIG Welding Wire for Dissimilar & High-Strength Steel Repairs
Product Overview:
• High-performance E312 stainless steel MIG wire for welding dissimilar steels and unknown alloys
• Ideal for joining tool steel, spring steel, armor plate, and manganese steel
• Excellent crack resistance and tensile strength due to two-phase microstructure
• Suitable for buffer layers in hard-facing applications and wear-resistant overlays
• Compatible with MIG (GMAW) process using argon-rich shielding gas
Technical Specifications:
• Wire Type: E312
• Diameter: 0.8mm
• Weight: 1kg spool
• Welding Process: MIG (GMAW)
• Polarity: DCEP (Direct Current Electrode Positive)
• Shielding Gas: Recommended – 98% Argon + 2% CO₂
• Applications: Dissimilar steel joints, unknown base metals, gear teeth, dies, springs, earthmoving equipment
• Finish: Tough, ductile welds with high tensile strength and minimal spatter
• Storage: Keep sealed and dry to prevent contamination
Chemical Composition (Typical Values):
• Carbon (C): ≤ 0.15% – Controlled to reduce cracking
• Chromium (Cr): 28.0–32.0% – High corrosion and oxidation resistance
• Nickel (Ni): ~8.0–10.0% – Enhances ductility and toughness
• Manganese (Mn): 0.5–2.5% – Supports arc stability and weld pool control
• Silicon (Si): ~0.90% – Aids slag formation and arc performance
• Molybdenum (Mo): ≤ 0.75% – Optional trace for added corrosion resistance
• Phosphorus (P): ≤ 0.04% – Controlled to prevent brittleness
• 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
