Chung Metal proudly produces and distributes Stainless Steel 321H Bars/Rods from its Đà Nẵng, Vietnam plant. This higher-carbon variant of SS 321 is engineered for greater strength and creep resistance at high temperatures. 321H is a titanium-stabilized austenitic stainless steel that’s renowned for its outstanding thermal stability as well as corrosion resistance in intergranular applications. Chung Metal’s 321H bars are manufactured with consistent quality and are suitable for critical uses under high-heat conditions. These rods come in different sizes and finishes and are appropriate for welding, machining, and other structural uses that call for long-term strength at elevated temperatures.
321H Stainless Steel generally consists of 17–19% chromium, 9–12% nickel, and 0.04–0.10% carbon, with titanium as an added stabilization agent. It has improved high-temperature strength and creep resistance over the general 321. Tensile strength varies from 550–750 MPa, yield strength from 210–300 MPa, and elongation is approximately 30–40%. The alloy is dependable in temperatures up to 900°C and resists intergranular corrosion under sustained heat exposure. It is non-magnetic, weldable, and maintains toughness upon welding or long-term thermal exposure and is a first choice material for high service conditions.

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.
321H stainless steel bars find extensive application in furnace components, heat exchanger tubes, boiler tubes, superheaters, chemical plant equipment, and thermal oxidizers. With their greater creep resistance and long-term strength, the bars find applications in the processing of oil and gas, power plants, aerospace, and refinery systems. 321H is particularly suitable for welded components operating in the temperature range of 538–900°C. It is also applied to high-temperature flue gas equipment and exhaust manifolds of engines. Chung Metal provides 321H rods in different forms that give strong support for industrial applications with high pressure and temperature.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Chung Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Da Nang, Vietnam
