ASTM A335 / ASME SA335 P91 Alloy Steel Seamless Pipe for High-Temperature Service​

 

 

A335/SA335 P91 is a ferritic alloy steel that has very high strength properties, which do not deteriorate with time, and are creep resistant. It is also called 9 Cr 1 Mo steel, or chrome moly pipe, based on its composition.

Compared to its predecessors, the T22 or P22 grade, grade P91 exhibits high strength, enduring temperatures up to 600 °C. The oxidation temperature limits are also higher allowing elements to be engineered with less thickness. This contributes to an almost 10 times higher thermal fatigue life and allows engineers to increase the operating temperature to a higher level, increasing efficiency.
