Nihonweld NHF-600R description: NHF-600R is an easy-to-use 100% recovery hardfacing alloy electrode. It deposits an air-hardening martensitic steel weld metal that exhibits high resistance to severe abrasive conditions and absorbs moderate impact forces.
Smooth running rutile electrode exhibiting excellent weld pool and slag control in all positions.
The deliberate alloying in the flux coating results in a high carbon martensitic weld matrix microstructure
NHF-600R is recommended where wear due to gouging, high stress grinding, low stress abrasion or erosion is encountered.
It is also used in the reclamation of worn-out parts and extending component life
Suitable for the hardfacing of mild and alloy steel components.
Deposit hardness: 650-700 HV
Suitable for A.C. / D.C. electrical supply. Minimum O.C.V. is 60V on D.C. electrode negative is preferred to reduce dilution from the parent metal.
The self air-hardening deposit is machinable by grinding only.
