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.
You’ll find Stainless Steel 904L Hollow Bars widely utilized in industries where superior corrosion resistance in harsh environments is essential. Typical applications include chemical processing equipment, heat exchangers, gas scrubbers, pharmaceutical machinery, and components for oil and gas refineries. They also play a crucial role in marine engineering, pulp and paper industries, and seawater handling systems due to their resistance to pitting and crevice corrosion. Plus, their impressive formability and weldability make them ideal for custom-fabricated parts and structural supports that are exposed to aggressive acids and chlorides, ensuring they last long and perform reliably.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
