ASME SA213 T91 alloy steel pipe is chrome moly steel with deliberate addition of chromium, molybdenum and vanadium. ASME SA213 is equivalent to ASTM A213. T91 alloy steel pipe has outstanding heat-resistance and creep strength. Besides, it has good resistance to corrosion, oxidation and fatigue rupture at elevated temperatures.

ASME SA213 T91 alloy steel pipe size:
1/8 in. [3.2 mm] in inside diameter to 5 in.[127 mm] in outside diameter, and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness.

ASME SA213 T91 alloy steel pipe having other diameters may be furnished, provided the pipe complies with all other requirements of ASME SA213/ASME SA213M specification.

ASME SA213 T91 alloy steel pipe chemical composition:

ASME SA213 T91 alloy steel pipe mechanical property:

ASME SA213 T91 alloy steel pipe is mainly for high temperature applications. It is primarily used for superheater and heat-exchanger in power plant boiler construction, headers, main steam pipeline, as well as the heating furnace piping in petrochemical industry.
