Stainless Steel 309 Tubing is primarily made up of chromium (22–24%) and nickel (12–15%), with small amounts of manganese, silicon, and carbon. This composition gives it exceptional resistance to corrosion and heat. It retains its strength even at high temperatures and shows impressive oxidation resistance up to 1093°C (2000°F). In terms of mechanical properties, it boasts a tensile strength of about 550 MPa, a yield strength of 205 MPa, and an elongation of 40% over 50mm. These characteristics make Stainless Steel 309 Tubing perfect for use in high-temperature and corrosive settings, ensuring it remains durable and structurally sound even under tough operational conditions.
