Phehlukwayo Metal provides stainless steel products that adhere to international standards, catering to industries like petrochemical, chemical processing, marine, and pharmaceutical with dependable, long-lasting solutions.
Stainless Steel 317L Hollow Bar is an austenitic stainless steel primarily made up of iron, chromium (18–20%), nickel (11–15%), molybdenum (3–4%), and a low carbon content (maximum 0.03%). This unique composition offers excellent corrosion resistance, especially against chlorides and acidic environments, along with impressive high-temperature strength and toughness. The material boasts a tensile strength of around 485–620 MPa, yield strength of 205–275 MPa, and remarkable ductility. Its austenitic structure ensures stability, good weldability, and reliable mechanical properties, making it ideal for critical applications that require long-term durability and resistance to chemical and environmental stress.
