Sanicro® 61 is a general-purpose, highly corrosion resistant alloy suitable for a wide range of high temperature applications such as:
Sanicro® 61 has superior resistance to, in particular, oxidation at high temperatures up to 1200°C (2200°F). The grade also offers excellent resistance to oxide scaling under cyclic thermal conditions, largely owing to the addition of aluminium.
Sanicro® 61 seamless nickel alloy tubing is supplied bright annealed in the outside diameter range 27.67-48.3 mm (0.75-1.5 in. nominal) and wall-thickness range 2.0-4.0 mm (0.079-0.160 in.).

The weldability of Sanicro® 61 is good. Suitable methods of fusion welding are manual metal-arc welding (MMA/SMAW) and gas-shielded arc welding, with the TIG/GTAW method as first choice.
For Sanicro® 61, heat-input of <1.2 kJ/mm and interpass temperature of <100°C (210°F) are recommended. A string bead welding technique should be used.
