Tariku Metals, a well-respected manufacturer and supplier located in Addis Ababa, Ethiopia, specializes in high-quality Stainless Steel 904L Hollow Bars that are built to withstand extreme corrosion and last for years. These hollow bars are crafted in line with international standards, ensuring they excel in tough chemical, marine, and high-temperature settings. Thanks to their rich nickel and molybdenum content, SS 904L Hollow Bars are highly resistant to pitting, crevice corrosion, and stress cracking. Tariku Metals prides itself on precision manufacturing, delivering perfect dimensions and a superior surface finish—making their 904L products the go-to choice for industries like chemical processing, pharmaceuticals, desalination, and marine engineering.
Stainless Steel 904L Hollow Bars consist of 19–23% chromium, 23–28% nickel, 4–5% molybdenum, 1–2% copper, along with trace elements such as manganese, silicon, and carbon. This low-carbon, high-alloy austenitic grade is known for its remarkable corrosion resistance, especially against sulfuric acid and environments rich in chlorides. SS 904L boasts a tensile strength of about 490–740 MPa, a yield strength of around 220 MPa, and an elongation of 35%. It maintains its toughness even in sub-zero and high-temperature conditions. The alloy’s non-magnetic properties, excellent weldability, and outstanding resistance to intergranular attack make it perfect for critical and high-performance industrial applications.

SS 904L differs from other stainless steels by its high resistance to corrosion, especially in acidic environments. It contains added copper, making it more resistant to pitting, crevice corrosion, and stress corrosion cracking compared to standard stainless steel alloys.
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.
Stainless Steel 904L Hollow Bars are extensively utilized in industries that require exceptional corrosion resistance and structural integrity. They are perfect for heat exchangers, pressure vessels, condensers, and piping systems in chemical and petrochemical facilities. The marine sector relies on them for pump shafts, seawater equipment, and components in desalination plants due to their resistance to chlorides. Additionally, they find applications in the pharmaceutical and paper industries for process equipment, showcasing their versatility and reliability in demanding environments.
