Descrizione di prodotto

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.
