With years of industry expertise, we at Semih Metals offer a wide range of products, including Stainless Steel 321 Rectangular Bars. Our bars are known for their excellent corrosion resistance, high strength and exceptional durability, making them ideal for various applications. We pride ourselves on delivering reliable products tailored to meet the specific needs of our clients. At Semih Metals, we are committed to providing quality and dependable solutions that exceed customer expectations.
Stainless Steel 321 Rectangular Bars are composed mainly of iron, chromium (17-19%), nickel (9-12%) and titanium (5 times the carbon content). This composition enhances resistance to corrosion, particularly in high-temperature environments. Mechanical properties include excellent tensile strength, yield strength, and hardness. It exhibits good weldability, formability, and resistance to oxidation and carburization. Advantages include resistance to intergranular corrosion, high-temperature stability, durability and suitability for applications in aerospace, chemical processing and heat exchangers, offering long-term performance in extreme conditions.

Yes, Stainless Steel 321 Rectangular Bars can be welded. They offer good weldability, particularly with proper preheat and post-weld heat treatment to prevent carbide precipitation.
Stainless Steel 321 Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent corrosion resistance. However, in harsh environments, extra coatings may be applied for enhanced protection.
Choose Stainless Steel 321 Rectangular Bars based on factors like strength, corrosion resistance, and temperature requirements of your application. Consider factors like weldability and environment exposure to ensure optimal performance.
Stainless Steel 321 Rectangular Bars are widely used in applications where high-temperature stability and corrosion resistance are critical. Common uses include aerospace components, heat exchangers, furnace parts and chemical processing equipment. They are also employed in the production of exhaust systems, aircraft manifolds and welded structures in the petrochemical industry. Their resistance to intergranular corrosion makes them ideal for use in welded components exposed to high temperatures, such as in power plants, cryogenic tanks and marine environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
