Welcome to Nimish Metal, your trusted partner in Safat, Kuwait, for premium stainless steel solutions. We take pride in supplying high-performance materials engineered for demanding environments. Our Stainless Steel 904L Hollow Bar exemplifies this commitment, offering unmatched resilience for the most challenging industrial applications. Recognized for its superior composition, this hollow bar is the go-to choice for professionals who cannot compromise on quality or longevity. We ensure a reliable supply of this exceptional material, backed by our expertise and dedication to serving Kuwait’s robust industrial sector.
The exceptional quality of 904L stems from its enhanced alloy composition, which includes a higher concentration of chromium, nickel, and molybdenum, along with added copper. This specific blend gives the hollow bar outstanding resistance to corrosion, particularly against sulfuric acid. Mechanically, it maintains good ductility and toughness, and can be readily welded and fabricated. This combination of chemical robustness and reliable mechanical strength makes it a fundamentally superior material compared to standard stainless steel grades.

SS 904L stainless steel consists of approximately 24-26% chromium, 19-23% nickel, 4-5% molybdenum, 1-2% copper, and small amounts of manganese, silicon, and carbon. The copper enhances corrosion resistance, particularly in acidic environments, while maintaining high strength.
The typical diameter range for SS 904L hollow bars varies from 10 mm to 300 mm, although custom sizes can be manufactured. These bars are available in various wall thicknesses, depending on specific application requirements and industry standards.
The unique properties of the 904L Hollow Bar make it indispensable across several critical industries. It is extensively used in constructing heat exchangers, ducting systems, and various components within chemical processing plants, where its resistance to corrosive acids is paramount. The pulp and paper industry also relies on it heavily. Furthermore, its durability makes it an excellent choice for structural applications in harsh marine environments and for fabricating pipes and fittings that handle aggressive fluids, ensuring long-term reliability and safety.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
