ASTM A335 P9 S50400 Alloy Steel Seamless Pipe Black Painting Beveled
ASTM A335 Grade P9 pipes have minimum yield strength of 205 MPA while their minimum Yield Strength is 415 MPA. These pipes have a minimum elongation percentage of about 30/20 4T. Phosphating, passivation, shot blasting, oil dip and varnishing are some of the surface treatments possible for A335 pipes.
These pipes can be tested by a variety of methods including flattening, surface and dimension, mechanical properties, hardness, chemical composition, inspection, bending, etc.
The P9 pipe is produced in common seamless, welded, and erw configurations. ASME SA335 Gr P9 Seamless Pipe is a single piece of metal that is produced after hot steel billets are passed through it. These pipes allow for a smooth flow of media due to the absence of any welds on their surface.

A335 is often called chrome moly pipe because of the chemical makeup of Mo and Cr. Mo increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel, and inhibits pitting.
Chromium (or chrome) is the essential constituent of stainless steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile, yield, and hardness at room temperatures. The composition chrome moly Alloy Steel pipe make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.
