Nimonic 75 Pipe

NIMONIC® alloy 75 (UNS N06075/W.Nr. 2.4951 & 2.4630) is an 80/20 nickel-chromium alloy with controlled additions of titanium and carbon. First introduced in the 1940s for turbine blades in the prototype Whittle jet engines, it is now mostly used for sheet applications calling for oxidation and scaling resistance coupled with medium strength at high operating temperatures. It is still used in gas turbine engineering and also for industrial thermal processing, furnace components and heat-treatment equipment. It is readily fabricated and welded. Some physical properties for NIMONIC alloy 75 are given in Tables 2-4. Thermal expansion data in Table 3 were determined on fully heat-treated material. The data are subject to a variation of approximately ±5% according to processing variables. The dynamic modulus data in Table 4 were obtained from fully heattreated cylindrical specimens vibrated in the flexural mode. The recommended heat treatments are quoted in the Heat Treatment section of this bulletin.
