Phehlukwayo Metal, a well-respected manufacturer and supplier located in Cape Town, South Africa, is all about crafting top-notch **Stainless Steel 904L Hex Bars**. These hex bars are celebrated for their outstanding corrosion resistance, strength, and durability, making them perfect for tough industrial applications. Phehlukwayo Metal prides itself on precision engineering, ensuring tight dimensional tolerances and an exceptional surface finish that meets global standards. Their Stainless Steel 904L Hex Bars find extensive use in chemical processing, marine environments, and heat exchangers, where the ability to withstand strong reducing acids and chloride-induced corrosion is essential for long-lasting performance and reliability.
The **Stainless Steel 904L Hex Bar** is made up of nickel (23–28%), chromium (19–23%), molybdenum (4–5%), copper (1–2%), along with manganese, silicon, carbon (≤0.02%), and iron as the main component. It boasts a tensile strength of about 490–710 MPa, a yield strength of roughly 220 MPa, and an elongation of 35%. This alloy is known for its excellent formability, weldability, and non-magnetic properties when annealed. Its low carbon content helps prevent carbide precipitation, which enhances its resistance to intergranular corrosion, even in harsh environments like sulfuric and phosphoric acids.

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** are widely used in industries that demand superior corrosion resistance and mechanical stability. You’ll find them in chemical and petrochemical processing equipment, marine hardware, heat exchangers, pulp and paper machinery, and pollution control systems. They’re also essential in the pharmaceutical and food processing sectors, where hygiene and chemical resistance are crucial. Thanks to their high nickel and molybdenum content, these hex bars are well-suited for use in seawater, acidic conditions, and high-temperature environments, ensuring they deliver long-lasting performance with minimal maintenance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
