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.
