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 downstream oil and gas, P5 and P9 grades are for refinery applications.
Alloying elements
The addition of Molybdenum (“Moly”) increases the strength of the steel and its elastic limit, enhances the steel resistance to wear, its impact qualities, and the hardenability. It also improves the resistance to softening, makes chromium steel less prone to embrittlement, and prevents pitting.
