Khaleed Stainless, a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, offers an impressive selection of stainless steel products that are celebrated for their quality and dependability. Among these offerings, Stainless Steel 321 Nuts stand out for their remarkable resistance to high temperatures and intergranular corrosion. These nuts are enhanced with titanium, which boosts their performance in both oxidative and corrosive environments. Crafted to deliver secure fastening solutions, Stainless Steel 321 Nuts are not only durable and strong but also perfectly suited for applications that require stability in elevated temperatures and tough working conditions.
These nuts are made from a blend of iron, chromium (17–19%), nickel (9–12%), and titanium for stabilization, which helps prevent carbide precipitation during welding or extended heating. This unique composition significantly enhances their resistance to corrosion and oxidation at temperatures reaching up to 870°C. On the mechanical side, they boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 40%, ensuring they remain tough, stable, and perform excellently in high-stress situations. Their ability to retain strength and resist scaling makes them perfect for critical fastening applications.
