📄 What is ASTM A335 P91 Pipe?

ASTM A335 Grade P91 is a seamless ferritic alloy steel pipe specifically designed for high-pressure and high-temperature service. It is made with 9% chromium and 1% molybdenum (Cr-Mo), delivering exceptional hardness, thermal resistance, and creep rupture properties.

Due to its superior metallurgical composition and excellent mechanical properties, P91 pipes are preferred in supercritical and ultra-supercritical boilers, as well as in heat exchangers, steam lines, and process piping in aggressive environments.
