P22 alloy steel pipe is a low alloy matieral specially designed for high-temperature environments. The main alloying element composition is chromium molybdenum high-temperature ferritic steel with Cr (1.9-2.6) and Mo (0.87-1.13).

P22 alloy steel pipe has excellent high-temperature performance, stable mechanical properties, and good welding performance. It can meet the strict requirements of working environments.

ASTM A335 Specification

ASTM A335 standard specification provides clear requirements and guidance for the design, manufacturing, and testing of seamless ferritic alloy nominal pipes for high-temperature use, ensuring the safety and reliability of these pipes in high-temperature environments.This standard specifies the room temperature tensile test, high temperature tensile test, compression test and bending test.

ASTM A335 P22 alloy pipes have excellent mechanical properties, which make them excellent in high-temperature and high-pressure environments.

Feature Of P22 Alloy Steel Pipe Material

P22 alloy steel pipe chemical components include carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), chromium (Cr), and molybdenum (Mo). The proportion and combination of these elements endow alloy pipes with excellent high-temperature performance, stable mechanical properties,making them outstanding in high-temperature working environments.
