321 321H Stainless Steel bar
Short Description:
Explore the key differences between 321 and 321H stainless steel bars. Learn about their high-temperature resistance, properties, and ideal applications.
321 stainless steel rod:
The 321 stainless steel bar is an austenitic stainless steel alloy containing titanium, which offers excellent resistance to intergranular corrosion even after exposure to temperatures in the chromium carbide precipitation range of 800°F to 1500°F (427°C to 816°C). This makes it ideal for use in high-temperature environments where the metal must maintain its strength and corrosion resistance. Common applications include exhaust manifolds, heat exchangers, and aircraft engine parts. The addition of titanium stabilizes the alloy, preventing carbide formation and ensuring long-term durability.

321 stainless steel bar applications
1.Aerospace: Components such as exhaust systems, manifolds, and turbine engine parts where exposure to high temperatures and corrosive environments is frequent.
2.Chemical Processing: Equipment like heat exchangers, chemical reactors, and storage tanks, where resistance to acidic and corrosive substances is essential.
3.Petroleum Refining: Piping, heat exchangers, and other equipment exposed to high-temperature petroleum and petrochemical processes.
4.Power Generation: Boilers, pressure vessels, and other components in power plants that operate under high heat and pressure.
5.Automotive: Exhaust systems, mufflers, and catalytic converters that require resistance to high temperatures and oxidation.
6.Food Processing: Equipment that must endure repeated cycles of heating and cooling, while maintaining hygienic conditions, such as in dairy and food processing machinery.
