petroleum and petrochemical industries in the pipeline system,
flow material line riser, collection pipe welding;
Suitable for welding of 25%Cr biphase stainless steel, such as
UNS 32550(AIloy255)S32750, S32760 and UNS J93370, J93380, J93404 and CD4MCuN castings.
Ripple fine
Low hydrogen super duplex stainless steel hand electrode,
the main components are 25.5Cr-9Ni-3.8Mo-0.7Cu-0.7W-0.25N
The weld metal is austenitic and ferritic biphase structure, and the corrosion resistance index is PRE>40.
It has high strength and good resistance to pitting and stress corrosion cracking.
Excellent welding technology, stable arc, little splash, easy to remove slag, beautiful forming, delicate ripples.
Easy slagging
