Product Specification

• Slagless design for cleaner welds
• Excellent heat and thermal shock resistance
• High impact strength for demanding applications
• Suitable for multi-layer build-up
• Extends service life of hot working tools

• Special alloy composition providing resistance to heat, thermal shock, and impact (formulated for hot tool service conditions).

• Remove all fatigued material by machining or grinding before welding.
• Preheat the base metal to 200°C – 300°C, depending on grade, size, and thickness.
• Perform post-weld heat treatment as required, depending on the specific job requirement.

• Maintenance and repair of hot working tools, especially hot forging dies.
