Located in Amman, Jordan, Sabra Metals is a trusted manufacturer and supplier of Stainless Steel 321H Hex Bars and Rods, specifically crafted for high-temperature and pressure-sensitive applications. These hexagonal bars are made from titanium-stabilized austenitic stainless steel, featuring a controlled higher carbon content that boosts creep strength when exposed to elevated temperatures. Sabra Metals prides itself on delivering precise hex dimensions, consistent metallurgy, and top-notch surface quality, all in line with international standards. With a reliable supply chain, the company caters to the power generation, petrochemical, refinery, and heavy engineering sectors both regionally and globally.
The Stainless Steel 321H Hex Bars and Rods are composed of chromium (17–19%), nickel (9–12%), titanium stabilization, and a higher carbon content compared to standard SS 321. This unique blend enhances resistance to intergranular corrosion while significantly boosting high-temperature strength and creep resistance. On the mechanical side, SS 321H provides greater tensile and yield strength than regular 321, along with commendable ductility and toughness. It maintains its mechanical stability and load-bearing capacity even when exposed to temperatures nearing 900°C for extended periods.

SS 321H Hex Bars/Rods are highly resistant to oxidation and intergranular corrosion due to titanium stabilization, making them ideal for high-temperature environments. They offer excellent strength, durability, and resistance to sulfur compounds, ensuring reliability in extreme conditions.
SS 321H Hex Bars/Rods are commonly used in aerospace, chemical processing, power generation, petrochemical, and pharmaceutical industries. They are ideal for high-temperature applications such as heat exchangers, pressure vessels, exhaust systems, and furnace components due to their excellent corrosion resistance.
SS 321H Hex Bars/Rods can be welded easily, thanks to their titanium stabilization, which prevents sensitization and intergranular corrosion. However, it's essential to use low-carbon filler materials to maintain the material's properties and prevent carbide precipitation. Pre-heating and post-weld heat treatment may be required for optimal results.
Stainless Steel 321H Hex Bars and Rods are frequently utilized in high-temperature, high-stress environments where standard stainless steels tend to falter. Common applications include components for pressure vessels, boiler parts, heat exchanger hardware, refinery equipment, and structures in power plants. Their hex shape makes them perfect for crafting nuts, bolts, and machined fasteners designed for elevated-temperature service. Additionally, they find extensive use in the petrochemical and chemical processing industries, where resistance to thermal cycling, oxidation, and corrosive welded environments is essential.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
