Effect of Alloy Elements on P9 Alloy Steel Pipes

  • Compared with the traditional petroleum cracking used seamless steel pipe, such as low alloy steel P11, P22, P5, the chemical composition of 9CrlMo (P9) has a higher content of Cr which reach an average content of 9% and the content of Mo element in an average of 1.0%.
  • The content of chromium has a benefit of improving the material high temperature oxidation corrosion resistance and high temperature strength.
  • The content of moly is to enhance the recrystallization temperature of solution matrix and enhance the high temperature strength, which has a benefit to improve the heat resistant strength of steel.
  • The content of C (carbon) is less than 0.15%, which is beneficial to welding. And other elements, the content of manganese (Mn) is 0.30-0.60%, which is used for deoxygenation and desulfurization, it’s helpful to improve the quality of steel.
  • The content of Si (silicon) is 0.25-1.0% which has high deoxidization ability, at the same time heat resistant steel containing silicon will form a dense and good protective oxide film under the high temperature to improve steel oxidation resistance.
  • Low contents of S and P, especially low S content, are helpful to enhance hydrogen sulfide stress corrosion resistance.
  • Therefore, 9CrlMo(p9) compared with traditional petrochemical steel has better resistances to high temperature oxidation, hydrogen sulfide stress corrosion and has advantages of high temperature resistance strength and so on, can be used for large petrochemical equipment.

ASTM A335 is a standard specification for seamless ferritic alloy-steel pipe for high-temperature service. The specification generally covers “chrome-moly” seamless pipes with remarkable resistance to corrosion and good tensile strength at high-temperature service. The testing requirements for these pipes include the following:

  • Transverse/longitudinal: tension and flattening, hardness, bend tests- for material which has been heat-treated in batch furnaces, these tests shall be made on the 5% of the pipes from each heat lot number. For smaller lots, one pipe at a minimum has to be tested
  • ASTM A335 Gr. P91 shall have a hardness of 250 HB / 265 HV (25 HRC)
  • Hydro testing: shall be applied to every length of pipe
  • The non-destructive electric test is optional
