SPEZILLA is one of leading manufacturers of high quality Stainless Steel 321 Pipes and Tubes which find application across diverse sectors. We offer qualitative SS 321 Pipes and Tubes in different sizes and shapes that are being designed as per the national and international standard quality of raw materials. Alloy 321 is a heat resistant, titanium stabilized, austenitic alloy that's commonly used for service in the 1000°-1600°F temperature range. Also known as UNS S32100, these pipes and tubes are primarily used in applications that involve continuous and intermittent service temperatures within the carbide precipitation range of 800°-1500°F. Recognized as WNR 1.4541, these SS 321 Seamless Pipes are very much similar to Grade 304, but with a titanium addition of at least five times the carbon content. Our Stainless Steel 321 Welded Tubes can be offered in customized length sizes and shapes, and are available at market leading prices.
