文摘：Supercritical, ultrasupercritical, and future advanced-ultrasupercritical coal-fired plant designs promise to utilize aggressive steam temperatures and pressures to greatly increase plant efficiency. At these advanced steam conditions, it will be advantageous to exploit high-strength and corrosion-resistant materials like Grade 92, 347HFG, Super 304H, and 310HCbN, among others (Ref. 15). The data presented in this article makes the case for a welding material, EPRI P87, which promises to not only increase the life of DMWs, but also be well suited to meet the demanding requirements of these future coal-fired plants. Based on the data shown here and presented elsewhere, it is clear that EPRI P87 is an enormously promising step forward in solving the issue of DMWs.
