Phehlukwayo Metal, a reliable supplier and manufacturer located in Cape Town, South Africa, proudly offers high-quality Stainless Steel 317 Hollow Bars designed for critical industrial applications that demand exceptional corrosion resistance and strength. This material is particularly well-regarded for its superior performance in harsh chemical environments. Stainless Steel 317 is an austenitic stainless steel that boasts a higher molybdenum content compared to 316, which translates to outstanding resistance against pitting and crevice corrosion. At Phehlukwayo Metal, we are dedicated to providing precision-engineered hollow bars that adhere to international standards, ensuring consistency, durability, and reliability for industries such as chemical processing, marine, and petrochemical.
These Stainless Steel 317 Hollow Bars are composed of roughly 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, along with a low carbon content that enhances weldability and reduces carbide precipitation. They deliver a tensile strength ranging from about 515–750 MPa and a yield strength of around 205 MPa. The hollow design not only cuts down on weight but also maintains structural integrity, making it perfect for high-performance applications. Thanks to its austenitic structure, this alloy offers excellent toughness, even in low temperatures, while the molybdenum content significantly boosts its resistance to chemical attacks and corrosion caused by chlorides.

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.
Stainless Steel 317 Hollow Bars find extensive use in environments where superior corrosion resistance is crucial, particularly in industries that deal with strong acids, chlorides, and other aggressive materials. Common applications include heat exchangers, chemical tanks, pressure piping, pulp and paper processing equipment, marine components, and pharmaceutical machinery. The hollow structure is especially beneficial for applications that require both strength and reduced weight.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
