Produkt-Beschreibung
X10CrMoVNb9-1 Alloy Steel Seamless Pipes for High-Temperature Service (T91/P91)
Grade T/P91 is a ferritic-martensitic steel containing 9% chromium and 1% molybdenum, micro-alloyed with vanadium and niobium, with controlled nitrogen content according to ASTM A335, A213, or EN 10216-2 standards under the designation X10CrMoVNb9-1.
Applications
On fossil-fueled 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 enables higher resistance to thermal fatigue
- Higher heat transfer and lower thermal expansion coefficients compared to austenitic steels
Available Specifications
Standard wall thicknesses: STD, 40, XH, 60, 80, 100, 120, 140, 160, XXH
Special customer-designated nominal and minimum wall thicknesses can also be furnished. Non-standard OD & ID are available.
Best Pipeline can offer 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.
