Semih Metals headquartered in Istanbul, Turkey, has made a name for itself fast becoming a leading supplier of high-end metals for various industrial applications. The Stainless Steel 321 Round Bars and Rods, which offers resistance to oxidation and intergranular corrosion, is included in our list of products. These bars and rods are made to perform at very high temperatures; hence very popular among users in aerospace, chemical processing, and thermal power industries. Our Stainless Steel 321 products meet international quality standards and can range from a large number of dimensions and finishes to have clientele-specific adaptations. Quality, precision, and affordability are foremost on the list at Semih Metals because, we ensure, every product comes with value and performance that equals or exceeds what customers expect.
Stainless Steel 321 Round Bars and Rods are high-performance alloy products manufactured from austenitic stainless steels. They are known for excellent corrosion resistance and high-temperature strength, and they have been stabilized with titanium to prevent precipitation of carbide during welding or while being subjected to high temperatures, making the elements ideal for high-stress applications. Their composition usually includes 17-19% chromium, 9-12% nickel, and traces of titanium (five times carbon content). Some other elements such as manganese, silicon, and nitrogen improve the mechanical properties while keeping carbon content low for enhancing weldability. These bars are considered ideal for aerospace, chemical processing, and heat exchangers in high-performance service operations.
