Khaleed Stainless is a well-respected manufacturer and supplier based in Riyadh, Saudi Arabia, known for its top-notch Stainless Steel 348 Flanges. These flanges are crafted for exceptional strength, durability, and resistance, making them perfect for extreme operating conditions. You’ll find them widely utilized in industries like petrochemical, oil and gas, chemical processing, and power generation, thanks to their remarkable ability to handle high temperatures and corrosive environments. Each Stainless Steel 348 Flange is manufactured with precision and adheres to international standards, ensuring secure pipe connections, leak-proof performance, and a long service life in critical applications.
The composition of Stainless Steel 348 Flanges includes iron, chromium (17–19%), nickel (9–13%), and columbium (niobium). This combination not only stabilizes the alloy but also boosts its resistance to intergranular corrosion. The addition of niobium is particularly beneficial as it prevents carbide precipitation during welding and thermal exposure, making the alloy a reliable choice for high-temperature applications. On the mechanical side, these flanges boast a tensile strength of around 550 MPa, a yield strength of 240 MPa, and impressive elongation, which together provide excellent toughness, thermal stability, and durability even under stress and elevated temperatures.
