A335/SA335 P91 is suitable for bending, flanging (vanstoning), and similar forming operations and for fusion welding. P91 is most commonly used in the power industry and petrochemical plants where fluids and gases are transported at extremely high temperatures and pressures.
P91's strength and high temperature endurance makes it ideally suitable for plants that operate on a cyclic basis - like combined cycle plants. Also, the reduction in thickness suits HRSG designers, in an HRSG the temperature head is limited and locating the coils in the heat transfer path is very critical.
P91 is the correct grade for:

  • Power generation
  • Petrochemicals
  • Gas processing
  • Petrochemical Plants
  • Heaters
  • Oilfield services
