| Popis: | While solid solution–strengthened alloys have inherent advantages for manufacturability, they do not have the high strength potential of age hardenable, γ′-strengthened alloys. One of these γ′ alloys, HAYNES 282 Alloy (Ni-19Cr-10Co-8.5Mo-1.5Al-2.1Ti), offers weldability and fabricability that is unmatched in wrought γ′ alloys of similar creep strength (eg, Waspaloy and Rene-41). With nearly twice the rupture strength at 700°C (1292°F) of the closest solid solution nickel alloys (like 617B), HAYNES 282 alloy offers both potential cost savings and improved manufacturability. Further, 282 alloy's excellent resistance to strain-age cracking during welding and good thermal stability offer a capacity for repairability that has proven to be the weak link in previous A-USC efforts. For these reasons, 282 alloy has been readily adopted by major gas turbine manufacturers and has become a leading candidate for emerging technology applications, like advanced ultra-supercritical steam, supercritical CO2, and others.
