NIFIL 600 is an S Ni 6082 / ER NiCr-3 type solid MlG welding wire, supplied precision layer wound, depositing
Ni-20Cr3Mn2.5Nb weld metal. Suitable for use with inert shielding gases.
- NIFIL 600 is used for welding of highly creep-resistant, heat and corrosion-resistant Ni-Cr alloys, where good toughness and ductility properties are required after post-weld heat treatment or prolonged operation at high temperatures.
- Use for 3%, 5% and 9% nickel steels to give good strength and tuoghness in LPG and LNG processing or storage plant.
- In sulphurous atmosphere the weld metal can be used <500°C. The thermal expansion coefficient between austenitic and ferritic steels, therefore this wire electrode is also suited for joining ferritic to austenitic steels (dissimilar) with operating temperatures or postweld heat treatment higher than 300°C.
- Also used for cladding of steels.
NIFIL 600 retains all-weld metal toughness -196°C, creep-resistant <800°C and is non-scaling <1000°C. Even at higher temperatures there is only limited carbon diffusion in the weld metal thus avoiding crack-prone carbide commissures in the weld interface of dissimilar joints.
