Chuck Metals is a leading manufacturing and supply chain based in Singapore, Singapore, specializing in high quality steel products for a range of industries. With years of experience, the company offers a wide range of metal solutions, including stainless steel, aluminum, and more. A standout product in their portfolio is the stainless steel 321H flat bar, known for its resistance to oxidation and high temperature environment Ideal for applications in medicine, power plants and space, Chuck Metals ensures each piece meets exacting quality standards. and offers a cost-effective solutions.
The stainless steel 321H flat bar is made of high carbon grade 321, designed for improved strength and resistance to high temperatures. It includes about 17-19% chromium, 9-12% nickel and a maximum of 0.04% carbon. The addition of titanium enhances its intergranular corrosion resistance. Mechanical properties of 321H include 505-750 MPa tensile strength, 205 MPa yield strength and 40% elongation. It exhibits superior resistance against oxidation, stress corrosion cracking and at high temperature environments; therefore, very ideal for use in industries of chemicals, aerospace and electrical

The primary alloying element in Stainless Steel 321H is titanium (Ti), which stabilizes the steel and prevents carbide precipitation during welding. It also contains chromium (Cr) for corrosion resistance and higher carbon content for increased strength at elevated temperatures.
Stainless Steel 321H is most suitable for high-temperature applications in the range of 427°C to 816°C (800°F to 1500°F). It offers excellent oxidation resistance and stability in these temperatures, making it ideal for heat exchangers and furnace components.
Typical dimensions of a Stainless Steel 321H flat bar range from 3mm to 150mm thickness, 25mm to 600mm width, and up to 6 meters in length. These dimensions vary based on manufacturer specifications and customer requirements.
Stainless Steel 321H Flat Bar is mainly used for high-temperature and corrosive environments because it provides superior resistance to oxidation and intergranular corrosion. Chemical processing, petrochemical, aerospace, and power-generating industries are the most frequent applications for this material. Such uses of stainless steel as a heat exchanger and boiler material, furnace part, exhaust system, include those with high strength resistance and minimal scaling. It is used even in aircraft and automobile part, besides providing the integrity of structure to high-temperature welded conditions, for excellent reliability and durability in more 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.
