CORDIFF 814

Flux-cored wire for heat- and thermal shock-resistant build-up of hot forging dies.

PRODUCT DESCRIPTION:

CORDIFF 814 is a flux-cored wire electrode depositing a rich Cr-Ni-Mo-V alloy weld metal with low carbon content. Designed for building up the working faces of composite hot forging dies, it provides excellent wear resistance at elevated temperatures, high hot strength, and superior thermal shock resistance. The deposit offers good machinability and achieves 44–48 HRc in the as-welded condition. Preheating of the base metal is recommended for best results.

Product Specification

• High Cr-Ni-Mo-V alloy for hot strength and wear resistance
• Excellent thermal shock resistance
• Good machinability despite high hardness
• Suitable for both large and small forging dies

• Rich Cr, Ni, Mo, and V with low carbon for balanced hardness, toughness, and hot strength.

• 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 life extension of hot working tools such as hot forging dies.
