Latham Steel, located in Hamilton, New Zealand, has built a solid reputation as a reliable manufacturer and supplier of Stainless Steel 317L Hollow Bars. These high-quality materials are specifically designed to offer outstanding corrosion resistance, strength, and durability. Stainless Steel 317L is a low-carbon, molybdenum-rich austenitic grade that shines in applications where superior resistance to pitting, crevice corrosion, and harsh chemical environments is essential. Latham Steel guarantees that every hollow bar adheres to strict international standards, ensuring precise, dependable, and long-lasting performance across various industries, including chemical processing, petrochemical, marine, and pharmaceuticals.
The composition of Stainless Steel 317L Hollow Bars includes about 18–20% chromium, 11–13% nickel, 3–4% molybdenum, and a maximum low carbon content of 0.03%. This blend provides remarkable corrosion resistance in chloride-rich and acidic settings while also maintaining impressive mechanical properties, such as a tensile strength ranging from 515 to 750 MPa and a yield strength between 205 and 450 MPa. The hollow bar design not only reduces weight but also simplifies machining and ensures consistent mechanical performance, making it perfect for piping, pressure vessels, and structural applications that demand both durability and precision.

The low carbon content of SS 317L reduces the risk of carbide precipitation at high temperatures, preventing grain boundary corrosion. This enhances its stability, weldability, and overall performance, making it more reliable in high-temperature environments, especially in corrosive conditions.
SS 317L Hollow Bars offer excellent corrosion resistance, particularly against chlorides and acidic environments, making them ideal for marine and chemical processing industries. Their high strength, durability, and resistance to pitting and crevice corrosion ensure long-lasting performance in harsh conditions.
Stainless Steel 317L Hollow Bars find extensive use in chemical and petrochemical plants, marine settings, pharmaceuticals, and desalination equipment. They are particularly well-suited for crafting shafts, tubes, valves, and pressure vessels that face corrosive conditions. With their exceptional corrosion resistance, mechanical strength, and lightweight hollow structure, these bars promise long-term reliability, minimal maintenance, and efficient performance. Engineers and manufacturers often turn to 317L hollow bars for critical applications that require robust, corrosion-resistant, high-performance stainless steel solutions.
