Lecong Stainless, located in Da Nang, Vietnam, has built a solid reputation as a manufacturer and supplier known for providing top-notch stainless steel solutions to markets around the world. With state-of-the-art facilities and a commitment to strict quality standards, the company focuses on producing Stainless Steel 309S Bars specifically for clients in Dubai, UAE. These bars are celebrated for their outstanding corrosion resistance, impressive mechanical strength, and durability even in high-temperature settings. Lecong Stainless prides itself on timely deliveries, precise engineering, and adherence to international quality standards, making it a reliable partner for industries that depend on trustworthy stainless steel products.
Stainless Steel 309S Bars are mainly made up of chromium (22%), nickel (12%), and a low carbon content, with iron serving as the base element. This unique blend boosts oxidation resistance and enhances toughness. They boast a tensile strength of around 550 MPa, a yield strength close to 205 MPa, and an elongation of about 40%. The low carbon content not only improves weldability but also minimizes carbide precipitation. Their mechanical properties ensure they can handle thermal stress, scaling, and creep, making them ideal for extended use in high-temperature conditions.
