NIDURIT 61

Specification

Description

• NIDURIT 61 is a chromium carbide hardfacing electrode for high abrasion and medium impact loads with recovery of 220%
• Excellent welding characteristics and easy slag removal

Application

• Highly wear resistant claddings on parts subject to strong grinding abrasion combined with medium impact
• Conveyor screws
• Scraper blades
• Mixer wings
• Sand pumps
• Sugar cane cutter knives

Remarks

Hold electrode as vertically as possible

Keep a short arc

Preheating is not necessary

For multipass applications, a cushion layer with NSS-307 or NHF-Cromang is recommended in order to prevent hardening racks in the weld deposit

Re-dry electrodes that have gotten damp for at 300ºC for 2 hours
