Phehlukwayo Metal, a top-notch stainless steel manufacturer and supplier located in Cape Town, South Africa, proudly offers high-quality Stainless Steel 310S Hollow Bars designed for tough industrial applications. Built to excel in extreme temperatures and corrosive settings, 310S is the low-carbon version of 310 stainless steel, which means it boasts better weldability and a lower chance of sensitization. At Phehlukwayo Metal, we make sure that every hollow bar meets international quality standards, providing our clients in industries like petrochemical, power generation, and thermal processing with reliable mechanical strength, corrosion resistance, and precise dimensions.
The composition of Stainless Steel 310S Hollow Bars includes about 24–26% chromium, 19–22% nickel, and a maximum carbon content of 0.08%. This unique blend offers outstanding resistance to oxidation and scaling at temperatures reaching up to 1100°C. Typically, 310S has a tensile strength ranging from 520 to 750 MPa, with a yield strength around 205 MPa. Thanks to its austenitic structure, it maintains good toughness and ductility, even in cryogenic conditions. The low carbon content is a plus, as it helps avoid carbide precipitation during welding, while the hollow design ensures strength without unnecessary weight—making it perfect for structural applications that require both durability and material efficiency.

The high chromium (25%) and nickel (20%) content in SS 310S enhances its resistance to corrosion by forming a protective oxide layer on the surface. This layer shields the material from aggressive environmental factors, preventing oxidation and corrosion in harsh conditions.
SS 310S Hollow Bars are commonly used in industries such as power generation, chemical processing, petrochemical, aerospace, and manufacturing. They are essential for components in high-temperature environments, including furnace parts, heat exchangers, boilers, reactors, and gas turbines.
Stainless Steel 310S Hollow Bars shine in high-temperature and high-stress environments where resistance to corrosion and oxidation is essential. You’ll find them commonly used in heat exchanger tubes, components for furnaces and boilers, burner pipes, thermal processing shafts, and equipment in petrochemical plants and power stations. Their hollow shape not only allows for efficient machining but also minimizes material usage without sacrificing strength.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
