Welcome to Sabra Metals, your trusted partner in Amman, Jordan, for premium stainless steel solutions. We take pride in manufacturing and supplying high-performance materials like the Stainless Steel 321 Hollow Bar, designed to meet the rigorous demands of modern industry. Our commitment is to provide not just a product, but a reliable foundation for your most critical projects, ensuring quality and durability you can count on from the heart of the Middle East.
The strength of our Stainless Steel 321 Hollow Bar lies in its unique composition, which includes titanium for superior stability. This addition grants it exceptional resistance to intergranular corrosion, especially after exposure to high temperatures. It maintains excellent mechanical properties, including high tensile strength and good ductility, allowing it to withstand significant stress and fabrication processes without compromising its structural integrity in challenging environments.

The addition of titanium in SS 321 stabilizes carbon, preventing the formation of chromium carbides at grain boundaries. This reduces the risk of intergranular corrosion, improving the alloy's resistance to corrosion in high-temperature environments and aggressive chemical conditions.
In aerospace, SS 321 Hollow Bar is used for exhaust systems, jet engine components, and fuel systems due to its high-temperature resistance. In the chemical industry, it's used for heat exchangers, reactors, and piping in corrosive environments.
This hollow bar is a go-to choice for demanding applications where heat and corrosion are major concerns. You’ll often find it forming the backbone of components in aircraft exhaust systems, industrial heat exchangers, and high-temperature piping. Its versatility also makes it ideal for the chemical processing industry and for manufacturing pressure vessels, where its reliable performance under stress ensures both safety and longevity for critical equipment.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
