Semih Metals, based in Istanbul, Turkey, is a reliable manufacturer and supplier of Stainless Steel 317L Rectangular Bars. They pride themselves on delivering top-notch stainless steel products that are designed for outstanding corrosion resistance, strength, and durability. Crafted with precision and under strict quality control, these rectangular bars boast excellent dimensional accuracy, a smooth surface finish, and dependable mechanical performance. Semih Metals guarantees that their Stainless Steel 317L Rectangular Bars meet the high standards required by industries like chemical processing, petrochemical, marine, food processing, and pharmaceuticals, where long-lasting corrosion resistance and structural integrity are crucial.
These bars are primarily made of iron, chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), with a low carbon content (≤0.03%) to avoid carbide precipitation during welding. This high-alloy makeup gives them remarkable resistance to pitting, crevice corrosion, and general corrosion in acidic and chloride-heavy environments. On the mechanical side, 317L offers solid tensile and yield strength, toughness, and reliable ductility. Its blend of corrosion resistance and mechanical stability makes it perfect for chemical, structural, and industrial applications that require long-term reliability.

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 find their place in various applications that need resistance to corrosion and chemical attacks. They’re commonly used in chemical processing equipment, heat exchangers, piping systems, storage tanks, and marine structures. Additionally, you’ll find them in pharmaceutical and food processing equipment, offshore platforms, and pollution control systems where hygiene and corrosion resistance are paramount. Thanks to their durability, mechanical strength, and ability to withstand harsh industrial conditions, Stainless Steel 317L Rectangular Bars are a go-to choice for many demanding applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
