haynes 230 superalloy in nigeria
Holy Child College is a Catholic secondary school for girls in Lagos, Nigeria. It was set up on 9 April 1945 by the Society of the Holy Child Jesus and run by the Roman Catholic Archdiocese of Lagos. The school is one of the 21 best boarding schools in Nigeria situated in the Ikoyi area of Lagos State. This school is equipped with state of the Corrosion Behaviours of Aged Haynes 282 and Inconel 718 in Haynes 282 and Inconel 718 are superalloy materials originally designed and used in aero- and land-based gas turbine engines. However, they are being considered and used in challenging environments such as nuclear power plants, chemical, and petrochemical plants due largely to their high creep strength and corrosion resistance at low and high temperatures.
Commercially available Haynes 230 was used for testing. Haynes 230 is a nickel-based superalloy, which exhibits good corrosion and creep resistance because of the addi-tion of chromium, molybdenum and tungsten. The Haynes 230 chemical composition is provided in Table 1. Single crystals were obtained from a seed, adopting the Typical Wrought Superalloys Haynes International Haynes 230 N06230 Ni-Cr-W-Mo alloy Low thermal expansion, Hot & cold-formable Combustion cans, transition ducts, flameholders, thermo-couple sheaths Haynes International High Temperature Low-Cycle Fatigue Behavior of Haynes® 230® Superalloy [pp. 573-581] L.J.
