Coreweld 80CNil is a metal cored wire designed for applications where good impact toughness is required.
Coreweld 80C-Ni1 is a metal cored wire for application where good low temperature impact toughness or weathering characteristics are required. It operates over a broad range of parameters, produces a smooth, spray transfer with minimal fume and spatter and is tolerant of light rust and millscale. The shielding gas used should be Ar 75-92% / 25-8% CO2.
