ASTM A335 GRADE P9 HOT ROLLED ALLOY STEEL SEAMLESS PIPES/TUBES

 

 

OVERVIEW

 

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as “P Grade”, chome moly pipe is popular in P-Grades P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.

 

Key to the composition of chrome moly alloy P9 is the addition of chromium and molybdenum. Chromium, or chrome, improves high-temperature strength, increases oxidation resistance and raises the tensile, yield and hardness at room temperatures. Molybdenum increases the strength, elastic limit, resistance to wear, impact qualities and hardenability. It increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is also the most effective additive for increasing high temperature creep strength, or creep resistance. It also enhances the corrosion resistance of steel and inhibits pitting.

 

 

APPLICATIONS

 

A335/SA335 P9 is a seamless ferritic alloy-steel pipe used for high-temperature applications. These pipes are versatile and can be used to transmit water, oil and natural gas. P9’s great performance properties make it suitable for energy-related applications.

P9 is suitable for:

  • Refinery
  • Machine building
  • Oil and gas
  • Power generation
  • Petrochemicals
  • Gas processing
  • Fertilizer
  • Sugar
