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.
Starc Metals’ Stainless Steel 904L Hollow Bars are extensively utilized in industries where high corrosion resistance and mechanical strength are crucial. In chemical and petrochemical plants, they serve as pipelines, heat exchangers, and process equipment that face acidic and chloride-rich environments. The marine sector uses them for offshore structures, ship components, and seawater applications. They are also essential in the pharmaceutical, food processing, and pulp and paper industries for hygienic, durable, and long-lasting components. Furthermore, 904L Hollow Bars find their place in construction and industrial manufacturing projects that require strength, reliability, and resistance to challenging conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
