High Temperature Properties Stainless SteelStainless steel have good strength and good resistance to corrosion and oxidation at elevated temperatures. Stainless steel are used at temperatures up to 1700° F for 304 and 316 and up to 2000 F for the high temperature stainless grade 309 (S) and up to 2100° F for 310 (S). Stainless steel is used extensively in heat exchanger, super-heaters, boiler, feed water heaters, valves and main steam lines
High-strength, corrosion-resistant steel can be an Dec 11, 2020 · Additionally, HSCR steel has a higher elevated temperature strength up to 950°F compared to Inconel alloy 718 and a higher elevated temperature strength up to 1200°F compared to Ti-6Al-4V alloy. HSCR steel also has greater workability and machinability, and better wear resistance.
Oct 01, 2008 · High-temperature fatigue properties of austenitic superalloys 718, A286, and 304L were investigated in region between 10 2 and 10 7 cycles. The alloys 718 and A286 are precipitation-hardening type austenitic superalloys, and 304L is a solid solution-hardening type austenitic steel. The fatigue strengths of alloys 718 and A286 in high-cycle region over 10 4 cycles showed a grain size effect.
Inconel 718® Nickel-Chromium Alloy Inconel 718 Super AlloyInconel 718® is a precipitation hardened nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F (704°C). The age-hardening response of Inconel 718 permits annealing and welding without spontaneous hardening during heating and cooling.
