Use

Iron-powder low-hydrogen electrodes for flat and fillet welding

Iron-powder low-hydrogen electrodes for flat and fillet welding

For nuclear power welding, such as 20MnHR.

The deposited metal contains 0.5% Ni–Ti–B, exhibiting excellent low-temperature impact toughness, and is used for welding LPG vessels, offshore structures in cold regions, and other critical structural applications.

Welding of Q345R HIC/16MnR HIC steel for resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSCC)

Better ductility and toughness than J507

It has a lower impurity content compared with J507.

Common-type all-position, low-hydrogen welding electrode

Low-hydrogen sodium type

Welding of Q345R HIC/16MnR HIC steel for resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSCC)
