Oerlikon Carbofil NiMo1 description: CARBOFIL NiMo1 is used to weld <620 MPa yield strength steels with excellent machanical properties. Because of its chemical composition the weld metal has good impact toughness down to -40C. Typical applications include the welding of higher strength fine grained steels used in the fabrication of oil field equipment, process plant and cranes, where low temperature weld metal toughness properties are also required.
