Inconel 617 Plates | UNS N06617 High Creep-Strength Plates for USC Boilers, Gas Turbines & Petrochemical Plants

In the second phase, the design team shifted critical sections to Inconel 617 Plates (UNS N06617, W.Nr. 2.4663), a solid‑solution strengthened Ni‑Cr‑Co‑Mo alloy whose datasheets describe “exceptionally high levels of creep‑rupture strength, even at temperatures of 1800°F (980°C) and above” together with good resistance to oxidising and carburising atmospheres, with typical plate properties around 760 MPa minimum tensile strength, 350 MPa yield strength, 30–35% elongation and reported retention of roughly 80% of tensile strength at 600°C, allowing designers to safely push steam temperatures and gas‑path metal temperatures without sacrificing life.
INCONEL alloy 617 is a nickel‑chromium‑cobalt‑molybdenum alloy developed to provide a combination of high‑temperature strength, metallurgical stability and oxidation resistance for service in the 540–1100°C range in gas turbines, USC boiler components and high‑temperature process equipment. Data from producers and alloy handbooks note that its high nickel and chromium contents make it resistant to a variety of both reducing and oxidising environments, while cobalt and molybdenum provide solid‑solution strengthening, aluminium contributes to oxidation resistance and the alloy retains useful strength under creep conditions at temperatures of 980°C and above, making it suitable for long‑term, high‑stress use at elevated temperature.
For procurement heads, mechanical and process engineers, fabricators, OEMs and hardware or industrial supply stores serving chemical, oil & gas, marine, pharma and power‑generation industries, Inconel 617 plates give a path beyond the limitations of ferritic steels and standard austenitic stainless steels in high‑temperature, high‑pressure and cyclic service. Mechanical property tables for plate show minimum tensile strengths around 760 MPa, minimum yield strengths around 350 MPa, elongation around 30–35%, with creep‑modelling work indicating superior creep resistance at 700°C compared with many other solid‑solution nickel alloys due to γ′ and carbide precipitates stabilised in the matrix.
