E-309L
Description:
E-309L is a CO 2 gas-shielded stainless steel flux cored wire with soft and stable arc, less splashing, beautiful appearance, easy slag removal, good welding process performance and full position welding. Deposited metal has good crack resistance.
use:
The same type of stainless steel structure and composite steel, dissimilar steel and other components used in the manufacture of synthetic fibers, petrochemicals and other equipment can also be used in the welding of nuclear reactor and pressure vessel inner wall transition layer and in-tower components.
Protective gas:
CO 2
