Product Description
Product Overview
ASTM A213 TP321 seamless heat exchanger tubes are manufactured from austenitic stainless steel with titanium stabilization. This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.
The titanium composition in SA213 TP321 material reduces density, resulting in lightweight construction while maintaining excellent corrosion resistance and high-temperature performance.
