Instruction
The E308LT1-1 is a titanium type CO, gas shielded ultra-low carbon stainless steel flux-cored welding wire, used for all-position welding, with small welding spatter, stable arc and less welding fume. The deposited metal is an austenite structure with a moderate amount of ferrite and low crack susceptibility. The deposited metal in the welding state has excellent corrosion resistance and mechanical properties, and has excellent resistance to intergranular corrosion.
Application
It is used for welding 18%Cr-8%Ni stainless steel in petrochemical and pressure vessels.
