Sadiki Metals, located in Kinshasa, Congo, stands out as a top manufacturer and supplier of high-quality stainless steel products, including Stainless Steel 304L Hollow Bars. These hollow bars are celebrated for their exceptional corrosion resistance, durability, and versatility, making them perfect for a variety of industrial and commercial uses. The 304L grade is a low-carbon variant of 304 stainless steel, which enhances its weldability while still providing robust corrosion resistance and mechanical strength. At Sadiki Metals, we ensure that every hollow bar adheres to international quality standards, offering dependable, high-performance solutions for industries that need long-lasting stainless steel components.
Stainless Steel 304L Hollow Bars are crafted from an austenitic stainless steel alloy that includes 18–20% chromium, 8–10.5% nickel, and a low carbon content (≤0.03%). This unique blend grants outstanding corrosion resistance, particularly in welded structures, while also preserving excellent mechanical properties. The material boasts a tensile strength of about 485–620 MPa, a yield strength of around 170–275 MPa, and an elongation rate exceeding 40%. With good toughness, dimensional stability, and oxidation resistance, 304L hollow bars are well-suited for structural, chemical, and food-grade applications.

The low carbon content in SS 304L minimizes carbide precipitation during welding, reducing the risk of intergranular corrosion. This enhances weldability, making it ideal for applications requiring extensive welding without compromising corrosion resistance or mechanical properties.
SS 304L has superior corrosion resistance compared to SS 304 due to its lower carbon content, which minimizes carbide precipitation during welding. This reduces susceptibility to intergranular corrosion, making SS 304L ideal for welded structures in corrosive environments.
Stainless Steel 304L Hollow Bars find extensive use in industries that demand corrosion resistance, durability, and weldability. Common applications include chemical processing equipment, heat exchangers, food and beverage machinery, pharmaceutical equipment, and marine components. They are also utilized in pipelines, valves, fasteners, and structural elements that are exposed to harsh environments. Sectors such as chemical, food processing, pharmaceuticals, and marine industries depend on 304L hollow bars to create long-lasting, high-performance components that uphold strength and hygiene.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
