SA213 T91 Tubes are in our stock normally Cold Drawn Seamless (CDS) T91 tubes, consistent mechanical T91 tubes and Hot Finished Seamless (HFS) T91 tubes, in a wide scope of sizes up to 100mm divider thickness.
The SA213 T91 Tubes are primarily used for boiler, superheater, and heat-exchanger. It is also an 9Cr-1Mo-V alloy steel with UNS designation K90901. Compared to its equivalent ASTM A335 P91, the chemical composition requirement of T91 steel is slightly different.
Grade T91 is a new ferritic alloy heat resistant steel developed based on grade T9 steel through the process of pure purification, fine crystallization metallurgy, microalloying and controlled rolling. The steel has good comprehensive mechanical properties, good welding properties and good process properties, suitable for high-temperature compression parts of the material.
