Latham Steel, located in Hamilton, New Zealand, stands out as a top manufacturer and supplier of Stainless Steel 317 Hollow Bars. They pride themselves on delivering high-quality materials that are built to resist corrosion, provide strength, and ensure durability. With a higher molybdenum content than the standard 316 grades, Stainless Steel 317 offers exceptional protection against pitting, crevice corrosion, and chemical attacks. Latham Steel guarantees that each hollow bar adheres to strict international standards, ensuring precise dimensions and reliable performance for industries like chemical processing, petrochemical, marine engineering, and pharmaceuticals, where dependability is key.
These Stainless Steel 317 Hollow Bars typically contain around 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, making them highly resistant to acidic and chloride-rich environments. On the mechanical side, 317 boasts a tensile strength ranging from 515–750 MPa and a yield strength of 205–450 MPa, along with good ductility and toughness. The hollow design not only reduces weight but also improves machinability and maintains uniform structural integrity, making it perfect for applications that demand precision and corrosion resistance.

SS 317 offers superior corrosion resistance compared to standard stainless steels like SS 304 and SS 316, especially in chloride-rich environments. It provides enhanced protection against pitting, crevice corrosion, and general corrosion, making it ideal for harsh chemical and marine applications.
SS 317 Hollow Bars typically contain 18-20% chromium, 3-4% molybdenum, 13-15% nickel, with small amounts of manganese, silicon, and carbon. This composition provides excellent corrosion resistance, particularly against chlorides, and enhances its strength at high temperatures.
You’ll find Stainless Steel 317 Hollow Bars commonly used in chemical and petrochemical plants, desalination systems, marine components, pharmaceutical equipment, heat exchangers, and fluid-handling systems. They’re particularly well-suited for crafting shafts, valves, pumps, and pressure piping that face harsh or corrosive conditions. Thanks to their impressive corrosion resistance, mechanical strength, and dimensional accuracy, these bars promise a long service life, lower maintenance needs, and reliable performance. Engineers and manufacturers often turn to 317 hollow bars for critical applications that require robust, high-performance stainless steel solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
