NIROD 600 is an S Ni 6082 / ER NiCr-3 type solid TlG welding rod depositing Ni-20Cr3Mn2.5Nb weld metal. Suitable for use with inert shielding gases.
NIROD 600 is used for the 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 joining 3%, 5% and 9% nickel steels to give good strength and tuoghness in LPG and LNG processing or storage plant. In sulphurous atmospheres the weld metal can be used <500°C. The dissimilar thermal coefficient of expansion between austenitic and ferritic steels means that NIROD 600 is also used for joining ferritic to austenitic steels (dissimilar) with operating temperatures or postweld heat treatment >300°C.
Also used for cladding of steels. NIROD 600 has cryogenic all-weld metal toughness down to -196°C, creep-resistant <800°C and non-scaling <1000°C. Even at elevated temperatures, there is only limited carbon diffusion in the weld metal thus avoiding crack-prone carbide commissures at the weld interface of dissimilar joints.
