Khaleed Stainless, a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, has built a solid reputation for providing top-notch stainless steel products that adhere to international standards. Among their extensive product lineup, the Stainless Steel 321 Flanges stand out for their remarkable resistance to high temperatures and intergranular corrosion. Thanks to the addition of titanium, these flanges retain their strength and structural integrity even when exposed to prolonged heat. Crafted for durability, reliability, and outstanding performance, Khaleed Stainless’s Stainless Steel 321 Flanges are a popular choice in piping systems across various industries, including chemical, petrochemical, power, and aerospace.
These flanges are primarily made up of iron, chromium (17–19%), nickel (9–12%), and titanium, which helps stabilize the alloy and prevents carbide precipitation. This specific composition boosts their resistance to oxidation and scaling at temperatures reaching up to 870°C. On the mechanical side, they boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an elongation of roughly 40%, ensuring they are tough, creep-resistant, and durable. Their ability to maintain mechanical properties even at elevated temperatures makes them perfect for heavy-duty and high-stress applications.
