,ASTM A249 heat exchanger tube
,19.05mm OD stainless steel tube
Product Introduction
321 stainless steel heat exchanger tube manufactured to ASTM A249 / A213, with outer diameter 19.05 mm and wall thickness 1.24 mm. Grade 321 is stabilized with titanium to prevent chromium carbide precipitation at high temperatures, providing dependable strength and corrosion resistance for continuous service up to 870°C. A stabilized thin-wall exchanger tube that resists carbide precipitation above 400°C, ensuring long service in refinery and high-temperature heat transfer duty.
Every pipe is produced under strict quality control, with full traceability from the raw coil or billet to the finished tube. Mill test certificates, chemical composition reports and mechanical property data are available with every shipment, and third-party inspection by SGS, BV or TUV can be arranged upon request.
