Stainless Steel 309 Nuts are primarily made up of chromium (22–24%) and nickel (12–15%), which provides outstanding oxidation resistance at high temperatures. This austenitic alloy features low carbon content to reduce carbide precipitation during welding. In terms of mechanical properties, SS 309 Nuts have a tensile strength of about 550 MPa, a yield strength of around 205 MPa, and an elongation of 40% over 50mm. These characteristics make them ideal for high-heat and corrosive environments, ensuring they maintain structural integrity and reliability. Their strength and resistance to scaling at elevated temperatures make them perfect for both industrial and architectural uses.
