ASME SA 335 Grade P9 Alloy Steel Seamless Pipes are Carbon Steel Pipes with subsequent addition of chromium, molybdenum and sometimes vanadium are known as chrome moly Pipes. ASME Specification alloy steel Pipes are used for high temperature service applications. Seamless Alloy Steel Pipes according to ASME SA 335 Grade P9 are reheated and furnished in full annlealed,isothermal annealed or normalised quenched and tempered condition. ASME SA 335 Grade P9 Alloy Steel Seamless Pipes have a typical chemistry with additions of 8.00-10.00 Chromium and 0.90-1.10 Molybdenum. Bearing minimum tensile strength of 415 Mpa ASME SA 335 Grade P9 Pipes have a minimum yield strength of 205 Mpa.
ASTM A335 P9 Alloy Steel Pipes
ASTM A335 P9 is the part of ASTM A335, The pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. The steel material shall conform to chemical composition, tensile property, and hardness requirements.
Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices.
The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.Both ends of each crate will indicate the order no., heat no., dimensions, weight and bundles or as requested.

Astm A335 standard specication for seamless ferritic alloy-steel pipe for high-temperature service
ASTM A335 standard is issued under the fixed designation A 335/A 335M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
Astm A335 standard specication for seamless ferritic alloy-steel pipe
This specification covers nominal (average) wall seamless alloy-steel pipe intended for high-temperature service (Mote 1). Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.
