ASTM A249 TP304L / UNS S30403 Stainless Steel Welded Tube Heat Exchanger Tube
ASTM A249 tubes are typically delivered in the annealed condition. Heat treatment may be necessary after welding to restore corrosion resistance and mechanical properties. These tubes undergo various tests such as hydrostatic or nondestructive electric tests to ensure they meet the specified requirements. Certifications documenting compliance with ASTM A249 standards are often provided with the tubes.
