Products Description
A335 P9 is a seamless ferritic alloy steel pipe, also known as ASTM A335 P9 chrome molybdenum pipe. Its key elements, chromium and molybdenum, enhance high-temperature strength, oxidation resistance, and wear resistance.
Ideal for power plants and petrochemical industries, P9 pipes support bending, flanging, and welding. They offer good mechanical properties, customization options, and suitability for high-temperature applications.

Mechanical Tests Specified of ASTM A335 P9 Alloy Steel pipe
Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. for small lots, at least one pipe shall be tested.
For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe.
