Aung Metals offers SS 317L Hollow Bars, renowned for their exceptional performance in various industries, particularly in pharmaceutical and food processing sectors. With superior corrosion resistance and excellent weldability, these hollow bars are designed to endure demanding environments. SS 317L Hollow Bars are highly valued in construction and marine applications for their remarkable durability. Their enhanced resistance to pitting, crevice corrosion, and high-temperature conditions makes them the ideal choice for harsh and challenging environments, ensuring long-lasting reliability in even the toughest applications.
SS 317L Hollow Bars have a chemical composition typically consisting of 18-20% chromium, 3-4% molybdenum, 12-15% nickel, with low carbon content (0.03% max), which helps prevent carbide precipitation. This composition provides excellent resistance to corrosion, particularly against chlorides and sulfuric acid. The mechanical properties of SS 317L include a tensile strength of approximately 570-700 MPa, yield strength of around 240 MPa, and elongation of 40-50%. These properties, combined with high weldability and resistance to pitting, make SS 317L suitable for harsh, high-temperature, and corrosive environments.
