Isis Metals is a well-respected manufacturer and supplier of Stainless Steel 321H Hex Bars and Rods, proudly based in Manila, Philippines. We specialize in delivering top-notch stainless steel products that are specifically designed to thrive in high-temperature and corrosive environments. Our Stainless Steel 321H Hex Bars and Rods are titanium-stabilized and feature a higher carbon content compared to standard 321, which boosts their creep strength and thermal stability. These bars and rods are known for their outstanding resistance to oxidation, intergranular corrosion, and scaling. Crafted to meet international quality standards, Isis Metals’ 321H products are perfect for industries like petrochemical, aerospace, power generation, and heat treatment, where durability and exceptional mechanical performance are a must.
Stainless Steel 321H Hex Bars and Rods are made up of chromium (17–19%), nickel (9–12%), carbon (0.04–0.10%), and titanium (≥5×C%), along with trace amounts of manganese, silicon, and phosphorus. The increased carbon content significantly boosts their high-temperature strength and creep resistance. These bars and rods boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%. With their excellent oxidation resistance, ductility, and thermal stability, Stainless Steel 321H Hex Bars and Rods are designed to perform reliably even under prolonged exposure to high temperatures and mechanical stress.

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 find extensive applications in heat exchangers, pressure vessels, chemical process equipment, exhaust manifolds, and furnace components, thanks to their remarkable high-temperature and corrosion-resistant properties. They are ideal for industries such as petrochemical, aerospace, oil refining, and power generation, where resistance to oxidation and scaling is crucial. Additionally, these bars and rods are utilized in boiler tubes, heat treatment equipment, expansion joints, and thermal processing machinery. The exceptional strength, weldability, and structural stability of Stainless Steel 321H make them a top choice for demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
