JIS DF2A-450B

Description and Applications
HJ450 is a low hydrogen type electrode, which is subjected to metal-to-metal abrasion.
Suitable for building up and repairing machinery which is used in civil engineering. For the welding of worn out parts which require high abrasion resistance and can be used without machinery.
 
Guideline in Usage
1.

Electrode should be re-dried at 100200℃ for 60 minutes before using.

2.

Remove dirt such as oil and dust before welding.
