  • Application¡G

Welding of 18%Cr-8%Ni stainless steels for chemical engineering plants and food processing apparatus.

  • CHARACTERISTICS
    CMG-308 is a gas metal arc welding wire to be used with Ar + 2%O2 shield gas. Arc is stable, bead appearance is beautiful with outstanding edge wetting and weldability is satisfactory. 19%Cr-9%Ni deposited metal contains an adequate amount of ferrite and shows excellent resistance to hot cracking.
