Semih Metals, based in Istanbul, Turkey, is a reliable manufacturer and supplier of Stainless Steel 321 Hex Bars and Rods. They focus on delivering top-notch stainless steel products that are built for strength, durability, and outstanding resistance to high-temperature oxidation and corrosion. Crafted with precision and under strict quality control, these hex bars and rods boast excellent dimensional accuracy, mechanical performance, and long-lasting reliability. Semih Metals guarantees that its Stainless Steel 321 Hex Bars and Rods meet the rigorous standards of industries like chemical, petrochemical, aerospace, power generation, and marine, where materials need to withstand extreme temperatures and corrosive environments.
The composition of Stainless Steel 321 Hex Bars and Rods primarily includes iron, chromium (17–19%), nickel (9–12%), and a touch of titanium (which acts as a stabilizer), along with carbon, manganese, and silicon. The inclusion of titanium helps stabilize the alloy against chromium carbide precipitation during welding, providing superior resistance to intergranular corrosion. On the mechanical side, 321 offers commendable tensile and yield strength, excellent toughness, and dependable high-temperature strength. Its blend of corrosion resistance, oxidation resistance, and mechanical reliability makes it a perfect fit for high-temperature applications in both structural and engineering settings.

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.
These Stainless Steel 321 Hex Bars and Rods find their way into various applications that demand resistance to high temperatures and corrosion. You’ll often see them in furnace parts, heat exchangers, boiler components, exhaust systems, chemical processing equipment, and aerospace structural components. They’re also utilized in marine and offshore settings where resistance to corrosive environments and thermal cycling is crucial. Thanks to their impressive mechanical strength, durability, and resistance to intergranular corrosion, Stainless Steel 321 Hex Bars and Rods are a go-to choice for many 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.
