Product Specification
• High alloy formulation (C-Cr-Ni-Mo) for strength and corrosion resistance
• Versatile application on austenitic stainless steels and dissimilar joints
• Good bead appearance and weldability
• Excellent metallurgical compatibility
• Chromium (Cr), Nickel (Ni), Molybdenum (Mo)
• Austenitic structure
• Low carbon content to minimize carbide precipitation
• Ensure proper gas flow surrounding the wire to prevent porosity.
• Gouge out or grind worn, damaged, and fatigued metal or cracks before welding.
• Use minimal weaving to achieve a flat,well-washed bead.
• Welding of 301, 302, 304, 305, 308, and 309 stainless steels
• Dissimilar joining: stainless steel to mild steel or low alloy steel
• Tough overlays on wear-affected or corrosion-prone surfaces
