A335 P9 Alloy Steel Pipe that covers “chrome-moly” seamless pipes with remarkable resistance to
corrosion and good tensile strength at high-temperature service. Generally, ASTM A335 P11, P22,
and P91 pipes are used in power generation and in downstream oil and gas, P5 and P9 grades are
for refinery applications.
How to define alloy pipes?
Alloy pipes are tubular with higher percentages, than standard carbon steel pipes, of alloying elements
as Molybdenum (Mo), Chromium (Cr), Nickel, etc. Actually, the ASTM A335 covers “low-alloy” steel pipes,
i.e. pipes that have a total amount of alloying elements below 5%. The addition of higher percentages of
alloying elements (example Nickel and Chromium) transforms the steel into higher alloys, like stainless steel,
duplex, up to super-alloyed materials like Inconel, Hastelloy, Monel, etc.
