What is Alloy Steel T91 Tubing?

The major composition of the Alloy Steel T91 Tubing is iron. Apart from iron, the main elements are chromium (8–9.5%), molybdenum (0.85–1.05%), vanadium, niobium, and a few small amounts of carbon, silicon, and manganese. The high-temperature strength, oxidation resistance, and creep properties of the alloy improvements were due to the additions of these alloying elements. The tubing achieves a tensile strength of more or less 620 MPa and a yield strength of approximately 440 MPa. Besides, it excels in impact strength, thermal joining capability, and surface strength, and therefore can last long even when subjected to harsh temperature and mechanical stress in advanced industrial installations.
