Crafted with precision using cutting-edge techniques, these rectangular bars boast excellent dimensional accuracy, a smooth surface finish, and consistent mechanical properties. Renowned for their remarkable resistance to pitting, crevice corrosion, and chemical attacks, Stainless Steel 317 Rectangular Bars are perfect for demanding industrial, chemical, and marine applications. Phehlukwayo Metal is committed to providing stainless steel products that adhere to international quality standards, catering to industries like petrochemical, chemical processing, pharmaceuticals, and marine with dependable, long-lasting solutions.
Stainless Steel 317 Rectangular Bars are made from austenitic stainless steel, primarily consisting of iron, chromium (18–20%), nickel (11–15%), molybdenum (3–4%), and a low carbon content (maximum 0.03%). This unique composition offers excellent resistance to corrosive environments, especially against chlorides and acids, while also providing high-temperature strength and toughness. The material has a tensile strength of around 485–620 MPa, yield strength of 205–275 MPa, and good ductility. Its ferrite-free austenitic structure guarantees stability, excellent weldability, and reliable mechanical performance, making it ideal for applications that require long-lasting durability and chemical resistance.

Stainless Steel 317 Rectangular Bars generally offer excellent corrosion resistance due to their alloy composition, but additional protective coatings may be beneficial in highly aggressive environments. For most applications, coatings are not necessary unless exposed to extreme conditions.
Choose Stainless Steel 317 Rectangular Bars based on factors like required corrosion resistance, strength, and the specific environmental conditions. Ensure the dimensions and grades meet the mechanical and chemical requirements of your application.
Yes, Stainless Steel 317 Rectangular Bars can be welded using standard welding techniques like TIG and MIG. However, proper heat control is essential to prevent carbide precipitation and maintain corrosion resistance.
Stainless Steel 317 Rectangular Bars find extensive use in applications that require superior corrosion resistance, mechanical strength, and durability. They are commonly utilized in chemical processing equipment, heat exchangers, pumps, valves, and marine components. This alloy is particularly well-suited for pharmaceutical machinery, petrochemical plants, and industrial piping systems that are exposed to acidic and chloride-rich environments. Additionally, Stainless Steel 317 Rectangular Bars are also employed in food processing equipment.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
