The SA213-T91 boiler tube is an advanced 9Cr-1Mo-V-Nb martensitic alloy steel seamless tube specifically developed for supercritical and ultra-supercritical boiler headers and main steam piping. With vanadium and niobium micro-alloying, T91 delivers dramatically improved creep strength at 600°C+ compared to traditional T22 grade.
