With a strong focus on precision, innovation, and keeping customers happy, the company specializes in crafting high-performance stainless steel products that adhere to international standards. The Stainless Steel 321H Bars and Rods are highly valued for their impressive strength, heat resistance, and durability, making them perfect for tough environments. Semih Metals makes sure that every product goes through rigorous quality control to ensure reliability, longevity, and outstanding performance in industrial and engineering applications.
These Stainless Steel 321H Bars and Rods are titanium-stabilized austenitic stainless steels, specifically designed to resist intergranular corrosion effectively. They consist of chromium (17–19%), nickel (9–12%), and titanium, with a higher carbon content than SS 321, which boosts their strength at high temperatures. These bars and rods showcase remarkable mechanical properties, including high tensile strength, good creep resistance, and exceptional toughness, even when the heat is on. They maintain their structural integrity in oxidizing conditions, making them ideal for long-term use in high-pressure and high-temperature settings across various industrial operations.

Stainless Steel 321H is a high-carbon version of 321 stainless steel. The higher carbon content in 321H improves its high-temperature strength, making it ideal for use in environments with temperatures over 800°C (1472°F). While both offer excellent resistance to oxidation and corrosion, 321H is particularly suited for applications with higher thermal stresses.
Stainless Steel 321H Bars and Rods are commonly used in industries such as aerospace, chemical processing, power generation, and marine environments. They are ideal for high-temperature applications such as heat exchangers, reactor cores, and furnace parts.
You’ll find Stainless Steel 321H Bars and Rods in industries where high-temperature performance and corrosion resistance are essential. They’re commonly used in petroleum refining, power generation, heat exchangers, chemical processing, and aerospace applications. These bars and rods are perfect for boiler components, expansion joints, furnace parts, and high-pressure piping systems. Thanks to their strength and resistance to oxidation, they’re also found in thermal processing equipment and jet engine components. Their durability, formability, and ability to handle extreme conditions make them a go-to material in heavy-duty industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
