Product Specification
• High ductility and toughness.
• Resists shrinkage stresses and impact loading.
• Suitable for overlaying old hardfacing or manganese steels.
• Fe-Cr-Mn austenitic structure.
• Gouge out or grind worn, damaged, and fatigued metal or cracks before welding.
• Preheat is generally not required, except for very heavy sections.
• Use minimal weaving to achieve a flat, well-washed bead.
• For manganese steel base metal keep temperature below 200oC
Repair of manganese steel buckets/shovels, hightensile tools/dies, crane wheels, undercarriage parts, gear wheels, and buffer layers.
