Product Introduction
321 stainless steel seamless pipe manufactured to ASTM A312 / A999, with outer diameter 88.9 mm and wall thickness 5.49 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. The stabilized grade resists intergranular corrosion in the sensitizing range, making this heavy-wall pipe reliable for refinery heaters and hot process service.
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.
