This product is ideal for homogeneous welding of nickel-based alloys and dissimilar joints with stainless steels, carbon steels, and Monel alloys. The high Ti content ensures exceptional resistance to porosity during on-site welding. Typical applications include desalination plants, piping systems, furnace equipment, and installations in the petrochemical and energy sectors. It is widely used for overlays on carbon steel as well. It boasts high mechanical strength and corrosion resistance at temperatures ranging from cryogenic conditions to over 980 °C. The weld deposits can be hardened by aging to enhance strength up to about 700 °C.

Nominal composition (wt. %) of this classification is 71 Ni, 16 Cr, 6 Fe, 3 Ti, and 2.5 Mn.

Fully austenitic microstructure with Ti-rich carbides.

Nickel base alloys to themselves and to stainless steels, carbon steels, Monel alloys and cryogenic 3% and 5% Ni steels.

• PROPRIETARY: Inconel® 600, 601, 800 (Special Metals)

Before proceeding with welding or heating nickel-based alloys, it is essential to clean the base metal. Oils, greases, paints, lubricants, marking pencils, temperature-indicating materials, thread compounds, and similar substances may contain sulfur or lead, which could cause brittleness in the base or weld metal if present during these operations. When welding fully austenitic and nickel-based steels, it is crucial to minimize heat input, interpass temperature, and dilution with the base metal. It is recommended to keep the heat input below 1.5 kJ/mm and not exceed an interpass temperature of 100 °C.
