Used for the welding of Super-Duplex stainless steels. This type is often used for root pass welding of 22%Cr standard duplex steels for critical applications, also for the welding of low carbon super martensitic 13%Cr steels.

Features

• The weld metal has a high resistance to pitting with a PREN>40 value combined with a good resistance to crevice corrosion as well as stress corrosion cracking.
• The nickel over matches the parent material by 2-3% to provide an optimum balance of austenite and ferrite in the as welded condition.

Typical Applications

• Offshore
• Paper industry
• Oil Industry

Shielding Gas

• I1 : Inert gas Ar (100%)
