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.
Neith Metals’ Stainless Steel 321 Hollow Bars are extensively utilized in applications requiring high-temperature and corrosion resistance. They are particularly suited for creating heat exchangers, furnace components, chemical tanks, exhaust systems, and parts for jet engines. Additionally, these bars find their place in power generation, food processing, and automotive machinery, where durability, weldability, and resistance to thermal fatigue are crucial. The hollow design not only enhances weight efficiency but also simplifies fabrication. Overall, Stainless Steel 321 Hollow Bars deliver reliable, high-performance solutions for industrial, chemical, and engineering applications.
