ASTM A335 ASME SA335 Alloy Steel Seamless Pipes
X10CrMoVNb9-1 Alloy Steel Seamless Pipes for High-temperature Service T91/P91
Product Definition
Grade T/P91 is a ferritic-martensitic (9% chromium, 1% molybdenum) steel micro-alloyed with vanadium and niobium, with controlled nitrogen content according to ASTM A335, A213, or EN 10216-2 standard under designation X10CrMoVNb9-1.
Primary Applications
On fossil-fuelled power plants, this grade is primarily used for high-temperature applications in superheater and reheater tubes, headers, and steam piping (main steam and hot reheat).
Performance Advantages
  • Excellent elevated-temperature strength and creep behavior up to 580°C - 600°C
  • 9% chromium content provides superior corrosion and oxidation resistance compared to grade 22
  • Reduced weight of boiler and piping components due to superior performance
  • Higher resistance to thermal fatigue
  • Superior heat transfer and lower thermal expansion coefficients compared to austenitic steels
Available Specifications
Materials available in industry standard designations: STD, 40, XH, 60, 80, 100, 120, 140, 160, XXH
Special customer designated nominal and minimum wall thicknesses can be furnished. Non-standard OD & ID are available.
Best Pipeline offers pipe from turned and bored forgings in accordance with Specifications A/SA369 when client requirements for size, wall thickness, quantity, or delivery cannot be met by material available under Specifications A/SA335.
A/SA369 material is manufactured in grades including FP11, FP22, FP5, FP9, FP91, and FP92 corresponding to the same grades listed for A/SA335.
