Rashid Metals, based in Muscat, Oman, has built a solid reputation as a reliable manufacturer and supplier of high-quality stainless-steel products designed to meet a variety of industrial needs. One of their standout products is the Stainless Steel 321 Flat Bar, which is celebrated for its impressive stability, resistance to corrosion, and ability to perform well in high-temperature settings. Crafted with cutting-edge manufacturing techniques and rigorous quality control, Rashid Metals guarantees that each flat bar adheres to global standards and meets customer expectations. With a strong focus on reliability, timely delivery, and technical know-how, the company confidently serves the petrochemical, construction, engineering, and fabrication sectors both in Oman and internationally.
The Stainless Steel 321 Flat Bar is an austenitic stainless-steel alloy that has been stabilized with titanium, making it resistant to carbide precipitation during welding and exposure to high temperatures. Its composition, which includes chromium, nickel, and titanium, enhances its resistance to intergranular corrosion. On the mechanical side, SS 321 boasts excellent toughness, good tensile strength, and dependable performance even at elevated temperatures. It maintains its structural integrity during thermal cycling and effectively resists oxidation. These characteristics make it an ideal choice for applications that demand long-lasting durability, heat resistance, and robust mechanical integrity in challenging industrial environments.

The primary alloying element in Stainless Steel 321 is chromium, typically comprising around 17-19%. Chromium provides corrosion resistance, while titanium is added to improve high-temperature stability and prevent carbide precipitation during welding or prolonged exposure to elevated temperatures.
Stainless Steel 321 is most suitable for temperatures ranging from 800°F to 1500°F (427°C to 815°C). It excels in high-temperature environments due to its titanium stabilization, which prevents carbide precipitation and maintains corrosion resistance under prolonged heat exposure.
Typical dimensions of Stainless Steel 321 flat bars vary, with widths ranging from 20 mm to 150 mm, thicknesses between 3 mm and 50 mm, and lengths up to 6 meters, customizable based on specific requirements.
Industries that require exceptional heat resistance, stability, and corrosion protection widely use the Stainless Steel 321 Flat Bar. It’s commonly found in heat exchangers, furnace components, exhaust systems, and high-temperature processing equipment. In sectors like petrochemical, oil and gas, and chemicals, SS 321 flat bars are preferred for piping, structural supports, and welded assemblies that face high thermal stress. Additionally, this material is suitable for aerospace components, food processing equipment, and construction projects that need reliable performance in varying temperature conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
