SA213 T91 Alloy Steel Boiler Tube
GNEE always emphasizes that our SA213 T91 seamless alloy tubes are manufactured in accordance with international quality standards. They have the best resistance to pitting and crevice corrosion. These steel tubes are made of the best raw materials to ensure their long-term durability.
SA213 T91 chrome-molybdenum steel tubes have good oxidation resistance and corrosion resistance due to the chromium content, and generally show excellent high temperature strength and creep behavior in the temperature range up to 600°C. SA213 T91 seamless tubes are made by seamless process and should be hot-worked or cold-worked as specified.
SA213 T91 alloy boiler tubes are mainly used to manufacture high-temperature superheaters, reheaters and other pressure parts of subcritical and supercritical power plant boilers with metal wall temperatures not exceeding 625°C, and are also used for pressure vessels and high-temperature pressure parts.
