Titanium (Ti) serves as the main alloying element in Stainless Steel 321H, stabilizing the steel and preventing carbide precipitation during welding. It also includes chromium (Cr) for corrosion resistance and a higher carbon content for improved strength at high temperatures.
Stainless Steel 321H works best for high-temperature uses within the range of 427°C to 816°C (800°F to 1500°F). It provides outstanding resistance to oxidation and stability at these temperatures, which makes it perfect for heat exchangers and furnace components.
The dimensions commonly available for a Stainless Steel 321H flat bar span 3mm to 150mm in thickness, 25mm to 600mm in width, and lengths reaching up to 6 meters. These measurements differ according to manufacturer specifications and customer requirements.
Stainless Steel 321H Flat Bar is primarily employed in high-temperature and corrosive settings because it offers excellent resistance to oxidation and intergranular corrosion. Chemical processing, petrochemical, aerospace, and power-generating industries are the most common applications for this material. Such applications of stainless steel as a heat exchanger and boiler material, furnace component, exhaust system, include those demanding high strength resistance and minimal scaling. It is applied even in aircraft and automobile parts, in addition to delivering structural integrity to high-temperature welded conditions, for outstanding reliability and durability in more challenging applications.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
