Nimonic 263: High Ductility Alloy for Gas Turbines

Nickel Nimonic 263 is a nickel-chromium-cobalt-molybdenum alloy. It was developed in 1971 by Rolls-Royce Ltd. as a replacement of Nimonic alloy 80A. It was designed so that it would offer improved ductility in welded assemblies, and to meet specific criteria in terms of proof stress and creep strength. Suitable both for cold forming and hot forming, the alloy Nimonic 263 is supplied in its annealed condition which provides excellent ductility and excellent fabrication characteristics. Due to its properties, alloy nimonic 263 finds use in high temperature and high strength applications, such as the hot section of gas turbines, both in aircraft and land-based applications. Application areas 1. The alloy is prone to internal cracks during forging, allowing heavy hammer blows. The ingot loading temperature is not higher than 700℃, the low temperature area is preheated for 20-30 minutes, the final heating temperature is 1150℃-1180℃, the opening forging temperature is not lower than 1050℃, and the final forging temperature is not lower than 950℃. 2. The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging. • Nimonic 263 is mainly used in the production of steam turbine rings, jackets and various sheets. • Pressure vessels, high-pressure storage tanks, high-pressure pipes, heat exchangers (chemical processing industry). • Oil and gas pipelines, heat exchanger fittings. • Sewage treatment system. • Pulp and paper industry classifiers, bleaching plants, storage and treatment systems. • Rotary shafts, press rolls, blades, impellers, etc. in high-strength and corrosion-resistant environments. • Ship or truck cargo box • Food Processing Equipment Chemical composition %
