Suppliers, Traders, Exporters and Stockists of Stainless Steel Grade 321 Round Bars & SS Rods
ARK Stainless is a leading supplier, stockist, and exporter of SS 321 Round Bars and Stainless Steel 321 Rods. Grade 321 stainless steel belongs to the austenitic class of the 300 series and is renowned for its excellent mechanical and corrosion-resistant properties. The Stainless Steel 321 Round Bar features a chemical composition similar to that of grade 304 but is stabilized with titanium, enhancing its performance during welding operations.
The inclusion of titanium in SS 321 Rods allows for the formation of stable titanium carbides at the weld seam, which provides superior resistance to intergranular corrosion and prevents sensitization of the grain boundary. This feature, combined with its ability to maintain mechanical properties under high temperatures, makes the ASTM A276 Type 321 Flat Bar a popular choice in demanding environments. Both the SS 321 Round Bars and ASTM A479 UNS S32100 Hex Bar exhibit excellent performance in cryogenic conditions, providing robust impact strength and mechanical properties.
The AISI 321 Threaded Bar is particularly valued for its superior creep strength at high temperatures, which allows it to perform effectively where other alloys, such as grade 304, might fail. Available in various sizes, shapes, and specifications, our SS 321 Round Bars are made from low carbon content steel, primarily consisting of nickel and chromium, making them ideal for a wide range of applications.
The versatile 321 Stainless Steel Hollow Bar is produced through hot working or welding, showcasing excellent resistance to corrosive reducers in harsh environments. Our 1.4541 Forged Round Bar is manufactured using advanced forging processes, ensuring good impact strength and dimensional accuracy. Designed for high-temperature applications, the AMS 5510 Bar operates effectively within a temperature range of 538 to 870 degrees Celsius.
With a minimum tensile strength of 515 MPa and yield strength of 205 MPa, our SS 321 Bars can be elongated by 35% while maintaining exceptional workability. The AISI 321 Stainless Steel Cold Rolled Bar is further processed to achieve enhanced strength and superior surface finish. Additionally, the ASTM A276 SS 321H Rod offers improved strength due to its higher carbon content, making it suitable for structural applications.
We export our high-quality Stainless Steel 321 Round Bars and SS 321 Rods to various countries, including the United Arab Emirates, Brazil, Russia, and many more.
