The addition of titanium in SS 321 stabilizes carbon, preventing the formation of chromium carbides at grain boundaries. This reduces the risk of intergranular corrosion, improving the alloy's resistance to corrosion in high-temperature environments and aggressive chemical conditions.
In aerospace, SS 321 Hollow Bar is used for exhaust systems, jet engine components, and fuel systems due to its high-temperature resistance. In the chemical industry, it's used for heat exchangers, reactors, and piping in corrosive environments.
Stainless Steel 321 Hollow Bars find their place in industries that require high-temperature strength, corrosion resistance, and durability. They are particularly well-suited for furnace components, heat exchangers, chemical processing equipment, pressure vessels, and aerospace applications. Their ability to resist intergranular corrosion makes them ideal for welded assemblies that are exposed to elevated temperatures. Additionally, they are utilized in marine environments, petrochemical plants, and power generation sectors. Stainless Steel 321 Hollow Bars offer a dependable mix of strength, durability, and heat resistance for critical engineering and industrial needs.
