Anucha Metals, a prominent manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 317L Hex Bars and Rods that are engineered to perform exceptionally well in tough environments. With a keen emphasis on durability, precision, and adherence to international quality standards, Anucha Metals is dedicated to meeting the varied needs of industries around the globe. Stainless Steel 317L, known for its low carbon content and molybdenum addition, is an austenitic stainless steel that offers remarkable resistance to corrosion, especially in harsh chemicals and marine settings. These hex bars and rods are commonly supplied to sectors like chemical, petrochemical, pharmaceutical, and marine industries, ensuring long-lasting and dependable performance.
The composition of Stainless Steel 317L Hex Bars and Rods primarily includes iron, along with 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, while keeping carbon content to a maximum of 0.03% to enhance weldability and minimize carbide precipitation. They also feature controlled levels of manganese, silicon, phosphorus, and sulfur. This alloy boasts a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, all while maintaining toughness across a broad temperature range. The inclusion of molybdenum significantly boosts resistance to pitting, crevice corrosion, and chemical attacks, making 317L a superior choice compared to many standard stainless steels.

SS 317L Hex Bars/Rods are commonly used in chemical processing, marine environments, pharmaceuticals, and food processing due to their excellent corrosion resistance and high strength. They are ideal for handling aggressive chemicals, including sulfuric acid, bleaching solutions, and pulp liquor. In construction, they are used for structural components and fittings.
SS 317L Hex Bars/Rods typically range from 6 mm to 100 mm in diameter, with lengths up to 6 meters. Tolerances generally conform to ±0.5 mm for diameter. These dimensions and tolerances ensure precision for machining, making them ideal for applications requiring high strength, corrosion resistance, and tight fit.
The high chromium (18-20%) and molybdenum (3-4%) content in SS 317L enhances its resistance to pitting and crevice corrosion by forming a passive oxide layer that protects against chloride-induced degradation. The low carbon content further reduces the risk of stress corrosion cracking, ensuring durability in harsh chloride environments.
Stainless Steel 317L Hex Bars and Rods find extensive application in industries that demand outstanding corrosion resistance and mechanical strength. In the chemical and petrochemical sectors, they are utilized in equipment, piping, and storage tanks that handle aggressive acids and solvents. The marine industry relies on them for components that are exposed to seawater and saline conditions. Additionally, the pharmaceutical and food processing industries favor these materials for sanitary equipment and processing systems where hygiene and corrosion resistance are paramount. They are also employed in power generation, condensers, and heat exchangers. With their durability and versatility, Stainless Steel 317L Hex Bars and Rods are an excellent choice for a wide range of applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
