ASTM A213 TP444 Stainless Steel Seamless Tube Heat Exchanger Tube Mechanical Properties

ASTM A213 TP444 stainless steel seamless tube has become an ultra-pure ferritic stainless steel pipe with excellent performance due to its excellent immunity to chloride stress corrosion cracking (Cl-SCC), top resistance to pitting and crevice corrosion, low thermal expansion and other excellent physical properties and affordable cost performance. This also makes ASTM A213 TP444 stainless steel seamless tube widely used in water treatment systems, heat exchangers, seawater desalination equipment and other industrial fields in chlorine-containing medium working environment. At the same time, during the use of ASTM A213 TP444 stainless steel seamless tube, the working temperature must be strictly controlled to avoid the brittle range of 370-540°C, and the standard process must be strictly followed during welding and cold processing.
