OK AristoRod 12.57

The non copper coated OK AristoRod 12.57 is a manganese-silicon bearing solid wire for welding of unalloyed steels, such as general structural, pressure vessel and ship building steels with a minimum tensile strength of 500 MPa, and for fine-grained carbon-manganese steels for the same purpose with a minimum yield strength of max 400 MPa. The electrode can be welded with Ar/20CO2 or with pure CO2 as the shielding gas. The wire electrode is suitable for welding at high currents.
