Isis Metals is a reliable manufacturer and supplier of Stainless Steel 317 Flat Bars, proudly based in Manila, Philippines. We specialize in delivering top-notch stainless steel products that meet the rigorous demands of various industrial applications. Our Stainless Steel 317 Flat Bars are celebrated for their outstanding resistance to corrosion and oxidation, particularly in environments rich in acids and chlorides. Designed for superior strength, weldability, and durability, these bars are perfect for critical applications in the chemical, petrochemical, and marine sectors. At Isis Metals, we guarantee that every Stainless Steel 317 Flat Bar adheres to international performance and reliability standards, providing long-lasting solutions for a wide range of engineering needs.
Stainless Steel 317 Flat Bars are made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), along with low carbon content and small amounts of silicon, manganese, and phosphorus. The elevated molybdenum content significantly boosts resistance to pitting, crevice corrosion, and chemical attacks in tough environments. These bars boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, ensuring excellent ductility and toughness. Even at high temperatures, Stainless Steel 317 Flat Bars maintain their mechanical strength and oxidation resistance, making them ideal for high-stress industrial applications.

Stainless Steel 317 is primarily composed of iron, chromium (about 18-20%), nickel (11-15%), and molybdenum (3-4%). It also contains small amounts of manganese, silicon, and carbon, offering excellent resistance to corrosion, especially in acidic environments.
Yes, Stainless Steel 317 Flat Bar is highly resistant to corrosion due to its high chromium and molybdenum content. It performs exceptionally well in aggressive environments, including exposure to chlorides and acidic conditions, making it suitable for harsh applications.
Yes, Stainless Steel 317 Flat Bar can be welded easily. Its composition, including high nickel and chromium, allows for good weldability. However, proper welding techniques and preheating may be necessary to prevent cracking or distortion in some cases.
Stainless Steel 317 Flat Bars find extensive use in the chemical and marine industries, where both high corrosion resistance and mechanical strength are crucial. They are perfect for applications such as evaporators, heat exchangers, condensers, storage tanks, and pressure vessels in chemical processing plants. Additionally, these flat bars are utilized in pulp and paper production, food processing, and pharmaceutical equipment, where cleanliness and durability are paramount. They also serve well in marine hardware, textile machinery, and pollution control devices. With their excellent formability and weldability, these bars are a versatile choice for various engineering projects.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
