Khaleed Stainless is a well-respected name in the stainless steel manufacturing and supply industry in Riyadh, Saudi Arabia. They offer a diverse selection of high-performance products designed specifically for industrial applications. Among their standout offerings is the **Stainless Steel 904L Flat Bar**, known for its remarkable corrosion resistance, excellent weldability, and impressive strength. These flat bars are crafted to exact dimensions and feature smooth finishes, making them perfect for fabrication, structural support, and handling chemicals. With a strong commitment to quality and reliability, Khaleed Stainless caters to various industries, including marine, chemical processing, food production, and pharmaceuticals, delivering durable solutions even in the most corrosive environments.
The Stainless Steel 904L Flat Bars are made from a high-alloy austenitic stainless steel that contains about 25% nickel, 20% chromium, 4.5% molybdenum, and a touch of copper. This unique blend provides exceptional resistance to sulfuric, phosphoric, and other harsh acids. In terms of mechanical properties, these bars boast a tensile strength ranging from 490 to 710 MPa and a yield strength of around 220 MPa. Their low carbon content significantly improves resistance to intergranular corrosion after welding, while the flat profile allows for easy fabrication, machining, and fitting. These bars excel under pressure and in extreme environmental conditions, ensuring longevity and structural integrity.

Stainless Steel 904L Flat Bar is widely used in chemical processing, oil and gas, marine, pharmaceutical, and pulp and paper industries due to its exceptional corrosion resistance, particularly in acidic, chloride-rich, and high-stress environments.
Stainless Steel 904L offers superior corrosion resistance compared to standard austenitic stainless steels, excelling in harsh environments with strong acids (sulfuric, phosphoric) and chloride exposure, due to its high nickel, chromium, and molybdenum content, reducing pitting and stress corrosion.
Yes, Stainless Steel 904L Flat Bar is highly suitable for marine environments due to its excellent resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making it ideal for shipbuilding, seawater equipment, and coastal structural applications.
Stainless Steel 904L Flat Bars find extensive use in applications that demand high corrosion resistance and mechanical stability. In the chemical processing sector, they serve as tank frames, support brackets, and welded components. In marine settings, these flat bars are perfect for deck structures and fittings that are regularly exposed to saltwater. The food and pharmaceutical industries rely on them for hygienic equipment and cleanroom structures. Additionally, they are utilized in heat exchangers, structural reinforcements, and pollution control systems.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
