Nestled in the industrial heart of Amman, Sabra Metals has built a reputation for precision and reliability, specializing in high-performance alloys. We are proud to offer the Stainless Steel 321 Flat Bar, a product engineered for resilience in demanding environments. Sourced and supplied with meticulous care, this grade is a cornerstone for projects requiring unwavering strength and superior resistance to high temperatures, making it a trusted choice for Jordanian industries and beyond.
The integrity of our Stainless Steel 321 Flat Bar begins with its composition, stabilized with titanium to prevent harmful carbide precipitation. This careful alloying results in impressive mechanical properties, including excellent tensile strength and good ductility, allowing it to be formed and fabricated with confidence. It maintains its corrosion resistance even after exposure to high temperatures, a key feature that sets it apart from other grades and ensures long-term structural integrity.

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.
This unique combination of strength and stability makes the 321 Flat Bar incredibly versatile. You’ll find it forming the backbone of critical components in heat exchangers, expansion joints, and high-temperature processing equipment across various sectors. Its reliability is also essential in architectural applications, aerospace frames, and exhaust systems, wherever materials must perform under sustained thermal stress without compromising their durability or safety.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
