AWS E308H-16

Description and Applications

HE308H is the same as HE308 electrode except that the allowable carbon content higher than HE308L. It is a lime-Titania type electrode with 19%Cr- 9%Ni deposited metal. Slag is easy to remove and arc is stable, spatters are less and bead appearance is beautiful.

HE308H is suitable for welding of SUS308H base metal.

 

Guideline in Usage

1. Electrodes should be re-dried at 250 300℃ for one hour before use
2. Excessively wide weaving may cause welding defects. Keep weaving width to less than 2.5 times electrode diameter.
