Smith Fittings, a reputable manufacturer and supplier located in Canberra, Australia, specializes in high-quality **Stainless Steel 317L Angles** that are celebrated for their outstanding corrosion resistance, strength, and durability, even in the toughest environments. Crafted with cutting-edge manufacturing techniques and top-notch materials, these angles boast impressive dimensional accuracy, a smooth surface finish, and long-lasting reliability. Smith Fittings guarantees that their Stainless Steel 317L Angles adhere to international quality standards, making them perfect for a variety of applications in industrial, chemical, marine, and structural settings. Their ability to resist pitting, crevice, and general corrosion makes them a go-to choice for demanding projects that require both strength and longevity in challenging conditions.
**Stainless Steel 317L Angle** is an austenitic stainless steel primarily made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), which significantly boosts its resistance to corrosion in harsh chemical environments. The low carbon content (the “L” grade) helps prevent carbide precipitation during welding, ensuring excellent weldability and structural integrity. These angles have a tensile strength of around 515 MPa, along with good ductility, toughness, and remarkable resistance to pitting and crevice corrosion. They remain stable under both mechanical stress and thermal conditions, making them ideal for structural and industrial uses.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
The stainless steel 317L angle provides excellent corrosion resistance, especially in aggressive environments with acids and chlorides, due to its high malybdenum content. It has excellent strength and stability, making it ideal for construction applications. The low carbon content reduces carbide precipitation during welding, resulting in stronger and longer lasting joints. The alloy provides excellent thermal and oxidation resistance, allowing it to be used at higher temperatures. Additionally, the 317L Angle is versatile, easy to manufacture, and requires little maintenance, making it cost-effective for the chemical, marine and industrial industries.
