Esab Dual Shield II 70-Ni1 H4 description: Dual Shield II 70-Ni1 H4 is an all-position, flux-cored wire designed to be used under 75%Ar/25%CO2 gas protection. It provides excellent low temperature toughness in both as-welded or stress-relieved conditions.
Dual Shield II 70-Ni1 H4 produces low diffusible Hydrogen levels – lower than 4ml/100g – over a wide range of welding parameters.
The smooth arc, fast-freezing slag, low spatter levels and easy slag release make this an ideal wire for the welding of steel plate in all positions.
Nickel content below 1% and Brinell hardness less than 200 meet the requirements for applications where resistance to stress-corrosion cracking is required.
DUAL SHIELD II 70-Ni1 H4 is used in the fabrication of storage vessels that need to be stress relieved to minimize the ocurrance of stress corrosion cracking (SCC).
