NHF-45

Specification

Description

• NHF-45 is a low hydrogen hardsurfacing electrode with exceptional abrasion resistance with moderate impact at temperatures up to 600°C
• Easy to use in flat and inclined upward position
• Low amount of slag
• High deposition rate at 235%

Application

• Hardsurfacing of parts subject to heavy abrasion with moderate impact
• Sinter breaker plants
• Scraping beaks in zinc industry
• Blast furnace charging equipment
• Vegetable oil press screws for palm or cocounut

Remarks

Preheat at 300ºC and over in general

Effective to postheat at 600°C and to slow cool after welding to prevent cracking

Dry the electrodes at 150-200ºC for 30-60 minutes before use
