JIS DF2B-450R

Description and Applications
HJ450R is a titanium type electrode. The hardness of deposited metal is approximately HV440~460.
Suitable for building up and repairing machinery to be used at civil engineering. Build-up worn out parts that need high abrasion resistance, and can be used without machinery.
 
Guideline in Usage
1.

Electrode should be re-dried at 100120℃ for 60 minutes before using.

2.

Remove dirt such as oil and dust before welding.
