Stainless Steel 317L is primarily composed of iron, with high levels of chromium (18-20%) and nickel (11-15%), along with molybdenum (3-4%) for enhanced corrosion resistance. It also contains small amounts of carbon, manganese, silicon, and phosphorus.
Yes, Stainless Steel 317L Flat Bar is highly resistant to corrosion, especially in harsh environments. Its high chromium, nickel, and molybdenum content enhances resistance to pitting, crevice corrosion, and general oxidation, making it ideal for chemical and marine applications.
Yes, Stainless Steel 317L Flat Bar can be welded easily using standard welding techniques such as TIG, MIG, and SMAW. Its low carbon content minimizes carbide precipitation during welding, ensuring strong joints and excellent corrosion resistance in the weld area.
The Stainless Steel 347 Flat Bar is commonly utilized in applications that demand high strength along with heat and corrosion resistance. Typical applications include petrochemical equipment, heat exchangers, boilers, pressure vessels, and exhaust manifolds. It’s also frequently used in power generation plants, refineries, and chemical processing facilities that experience continuous thermal cycling. In the realms of fabrication and construction, these flat bars serve as structural supports, frames, and components where long-lasting durability and dependable performance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
