Product Description

ASTM A335 P91 Alloy Steel Pipe Cold Drawn T91 Alloy Steel Tube

Product Overview

X10CrMoVNb9-1 Alloy Steel Seamless pipes for High-temperature Service T91/P91 (X10CrMoVNb9-1)

Material 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 the designation X10CrMoVNb9-1.

Primary Applications

On fossil-fuelled power plants, this grade is mainly used for high-temperature applications in superheater and reheater tubes, headers, and steam piping (main steam and hot reheat).

Performance Characteristics

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 Sizes: 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 dimensions are available.

Alternative Manufacturing Options

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.
