Al Summan Metals, a leading manufacturer and supplier based in Dubai, UAE, has built a strong reputation for its high-quality Stainless Steel 321 Flat Bars. Engineered to deliver exceptional resistance to intergranular corrosion and oxidation, particularly under high-temperature conditions, these bars set a high standard. Through advanced manufacturing processes and stringent quality control, Al Summan Metals takes pride in offering precision, durability, and compliance with global standards. Available in numerous sizes and finishes, the Stainless Steel 321 Flat Bars are ideally suited for sectors such as chemical processing, aerospace, and power generation, where dependability, strength, and enduring performance in demanding environments are crucial.
These bars consist of chromium (17–19%), nickel (9–12%), carbon (up to 0.08%), together with manganese, silicon, and stabilizing titanium. Including titanium helps stop carbide precipitation during welding and heat exposure, enhancing their corrosion resistance. Featuring a tensile strength of roughly 515 MPa, a yield strength of about 205 MPa, and an elongation of 40%, they deliver remarkable mechanical strength, solid creep resistance, and thermal stability, which makes them ideal for prolonged use in high-temperature environments.

Chromium serves as the main alloying element in Stainless Steel 321, usually making up about 17-19%. Corrosion resistance comes from chromium, whereas titanium is included to enhance high-temperature stability and stop carbide precipitation during welding or extended exposure to high temperatures.
Stainless Steel 321 works best in the temperature range of 800°F to 1500°F (427°C to 815°C). It performs exceptionally well in high-temperature settings thanks to its titanium stabilization, which stops carbide precipitation and preserves corrosion resistance during extended heat exposure.
The dimensions of Stainless Steel 321 flat bars typically differ, with widths spanning from 20 mm to 150 mm, thicknesses ranging between 3 mm and 50 mm, and lengths reaching up to 6 meters, adjustable according to particular needs.
Stainless Steel 321 Flat Bars are widely used across industries that require heat resistance and protection against corrosion. They work exceptionally well for producing parts such as heat exchangers, furnace components, pressure vessels, and exhaust systems. Owing to their dependable performance in high-temperature settings, these bars are also employed in refineries, petrochemical plants, and thermal processing equipment. In addition, Stainless Steel 321 Flat Bars serve the aerospace, marine, and food processing industries, where toughness, weldability, and oxidation resistance are essential for efficient and durable operations.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
