Description

ASTM A213 T91 Alloy Steel Tube For Power Plants



Specification



ASTM A213 T91 alloy steel tube offers excellent high-temperature strength, oxidation resistance, and creep resistance, making it ideal for demanding applications in power plants, boilers, superheaters, and heat exchangers. It is a 9% Cr-1% Mo alloy, micro-alloyed with Vanadium, Niobium, and Nitrogen, which results in a tempered martensitic microstructure and provides superior performance at elevated temperatures and pressures.

A Maximum,uness range or minimum isindicated. Where eipses () apear in thistable, there is no requiremen,and analysis for the elementneed not be detemined or reported.
B lt is permissible to order T2 and T12 with a sulfur content of 0.045 max. See 16.3.
C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material
test report.
D Applies to both heat and product analyses.
E The terms Niobium (Nb) and Columbium (Cb) are alternate names for the same element.
F Grade T93 shall have a Nb + Ta content of 0.05-0.12 %.
G Chromium-Nickel Balance is defined as CNB = (Cr + 6Si + 4Mo +1.5W + 11V + 5Nb + 9Ti + 12AI) - (40C + 30N + 4Ni + 2Mn + 1Cu).
