SS 904L Hex Bar offers excellent corrosion resistance, especially against pitting, crevice, and stress corrosion cracking. Its high nickel and chromium content make it ideal for harsh environments like chemical processing, marine, and power plants. The hexagonal shape provides enhanced strength and machinability, ensuring durability and reliability in industrial applications.
SS 904L outperforms many stainless steels, such as 304 and 316, in corrosion resistance due to its higher nickel and molybdenum content. This composition enhances resistance to chloride-induced pitting and crevice corrosion, making it ideal for environments with high chloride concentrations or acidic exposure, such as chemical and marine applications.
SS 904L Hex Bar is commonly used in the chemical, petrochemical, marine, and pharmaceutical industries. It is ideal for applications such as heat exchangers, reactor vessels, pressure vessels, and piping systems, where resistance to corrosion, especially in acidic and chloride-rich environments, is critical for long-term durability and performance.
Stainless Steel 904L Hex Bars find their place in various applications that require high corrosion resistance and structural integrity. They’re commonly used in chemical processing equipment, heat exchangers, storage tanks, valves, offshore platforms, and seawater handling systems. Their exceptional resistance to acids, chlorides, and aggressive chemicals makes them ideal for industries like pulp and paper, pharmaceuticals, and pollution control. Additionally, they are utilized in shafts, flanges, and structural components that demand high durability and precision. With their impressive strength and corrosion resistance, these hex bars are built to last.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
