Anucha Metals, a reputable manufacturer and supplier located in Bangkok, Thailand, specializes in high-quality Stainless Steel 317L Rectangular Bars that adhere to international quality standards. With a strong background in precision engineering and a commitment to durability, Anucha Metals guarantees that its products provide long-lasting performance even in the toughest industries. Stainless Steel 317L is a low-carbon, molybdenum-rich austenitic stainless steel, celebrated for its outstanding corrosion resistance in harsh chemical environments and marine settings. These rectangular bars find extensive use in the chemical, petrochemical, pharmaceutical, and marine sectors, where strength, reliability, and resistance to corrosion are essential.
The composition of Stainless Steel 317L Rectangular Bars includes iron, 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a maximum carbon content of 0.03% to enhance weldability and minimize carbide precipitation. They also have controlled amounts 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 addition of molybdenum significantly boosts resistance to pitting and crevice corrosion, making it a superior choice compared to many standard stainless steel grades.

Choose Stainless Steel 317L Rectangular Bars based on the level of corrosion resistance needed for your application and the material’s strength requirements. Consider factors like temperature, pressure, and the potential for exposure to harsh chemicals or marine environments.
Stainless Steel 317L Rectangular Bars generally do not require additional corrosion protection coatings due to their inherent resistance to corrosion, especially in acidic and chloride environments. However, in highly aggressive conditions, coatings may be considered for extra protection.
When selecting Stainless Steel 317L Rectangular Bars, consider factors like corrosion resistance in aggressive environments and required mechanical properties such as strength and weldability. Also, evaluate the specific application conditions, including temperature and chemical exposure.
Stainless Steel 317L Rectangular Bars are extensively utilized in industries that demand exceptional corrosion resistance and high mechanical strength. In chemical and petrochemical facilities, they are employed for tanks, piping systems, and equipment that handle strong acids and corrosive solutions. The marine industry uses them in shipbuilding and components exposed to seawater. In the pharmaceutical and food processing sectors, they are essential for sanitary systems, storage vessels, and process equipment. Additionally, they are applied in power generation for condensers and heat exchangers. Their durability, weldability, and resistance to harsh environments make Stainless Steel 317L Rectangular Bars a top choice for critical applications.
