HF-500

Welding Electrode HF-500

PREMIARC

Welding Electrode HF-500 KOBE STEEL is a high-quality hardfacing electrode for maximum protection against abrasion, ideal for mining equipment and heavy industry.

Classification

JIS Z3251 DF2B-500-B

Product Description

Welding Electrode HF-500 is a specialized electrode for hardfacing applications formulated to provide maximum protection against abrasion wear.

With the ability to produce a durable hard metal coating, HF-500 is perfect for use on the surfaces of heavy equipment, excavator buckets, crushers, cutting blades, and other industrial components that experience high friction.

This welding electrode is capable of forming deposits with stable hardness and a tough metallurgical structure, making it a reliable solution for increasing equipment service life.

The HF-500 is also designed to be easy to apply, either in a flat or slightly tilted position, with neat welding results and minimal spatter.

Guidelines for welding

Guidelines for better welding

  • It is recommended to re-dry at 300 - 350℃ for 30 - 60 minutes before use
  • Keep the arc length as short as possible
  • Use the step-back method to start the bow to prevent blowholes
  • Control the width of the webbing less than 3 - 4 times the electrode diameter
  • Rust, oil and other elements must be completely removed on the base metal before welding
  • Proper preheating and inter-pass temperatures are important to minimize cracking
  • Heating the weld at 300 - 350℃ for 10 - 30 minutes to prevent cold cracking
  • Post-hardening heat treatment (PWHT) at 550 - 750℃ is effective to prevent cold cracking and distortion
