Isis Metals stands out as a reliable manufacturer and supplier of Stainless Steel 321 Hex Bars and Rods right here in Manila, Philippines. We pride ourselves on delivering top-notch stainless steel solutions tailored for critical industrial needs. Our Stainless Steel 321 Hex Bars and Rods are made from titanium-stabilized austenitic stainless steels, which offer remarkable resistance to intergranular corrosion, especially after being exposed to high temperatures. They’re built to perform consistently in environments where oxidation and thermal stress are common. With their exceptional durability, strength, and weldability, our Stainless Steel 321 Hex Bars and Rods are widely utilized in sectors like chemical processing, aerospace, and power generation.
Our Stainless Steel 321 Hex Bars and Rods are crafted from a blend of chromium (17–19%), nickel (9–12%), and titanium (≥5×C%), along with trace amounts of manganese, silicon, and carbon (≤0.08%). The titanium plays a crucial role in stabilizing against carbide precipitation, which boosts resistance to intergranular corrosion. These bars and rods showcase a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, ensuring they are both formable and ductile. They maintain impressive oxidation resistance and mechanical integrity, even at high temperatures, making them perfect for long-term, high-heat applications.

SS 321 hex bars/rods are highly suitable for high-temperature applications due to their excellent resistance to oxidation and scaling, particularly in environments above 900°C. The addition of titanium stabilizes the material, preventing carbide precipitation, and enhancing its resistance to intergranular corrosion, making it ideal for aerospace and industrial applications.
SS 321 hex bars/rods are commonly used in industries requiring high-temperature resistance, such as aerospace, chemical processing, and power generation. Applications include exhaust systems, heat exchangers, furnace components, and reactors. Their resistance to corrosion, oxidation, and scaling makes them ideal for environments with elevated temperatures and aggressive conditions.
SS 321 hex bars/rods can be welded easily, but special care is needed to prevent carbide precipitation. Preheating and post-weld heat treatment are recommended to avoid weld embrittlement. Using titanium-stabilized filler metals helps maintain the alloy’s resistance to intergranular corrosion, ensuring weld integrity in high-temperature applications.
Stainless Steel 321 Hex Bars and Rods find extensive use in industries like aerospace, petrochemical, chemical processing, and power generation. They’re perfect for applications such as heat exchangers, manifolds, exhaust systems, furnace parts, expansion joints, and pressure vessels, where heat and corrosion resistance are essential. Their outstanding weldability and mechanical stability make them ideal for boilers, refineries, and thermal processing plants. Plus, these bars and rods are a top choice in pharmaceutical and food processing equipment, ensuring hygiene and durability for the long haul.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
