Stainless Steel MIG Wire

CMG-308

AWS ER308
JIS Y308

• Application：

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.
  　

• GUIDELINE IN USAGE
  When high X-ray quality is required, stable spray transfer mode should be maintained with low current and slow welding speed using a pulsed arc power source.
