Khaled Stainless, a reputable manufacturer and supplier based in Cairo, Egypt, specializes in top-notch Stainless Steel 347H Fasteners that are designed for high-temperature and high-stress environments. This high-carbon, niobium-stabilized austenitic stainless steel is crafted to resist carbide precipitation, ensuring exceptional creep strength even under prolonged heat exposure. At Khaled Stainless, we prioritize precision threading, accurate dimensions, and adherence to global fastener standards, resulting in robust and dependable fastening components. Our 347H Fasteners find extensive use in industries like petrochemical, power generation, refineries, and chemical processing, where secure joints, long-lasting stability, and strong corrosion resistance are crucial.
Stainless Steel 347H Fasteners are composed of 17–19% Chromium, 9–13% Nickel, and a higher Carbon content compared to standard 347, along with Niobium/Tantalum stabilizers that help prevent carbide formation during high-temperature applications. This alloy boasts impressive tensile and yield strength, enhanced creep resistance, and strong oxidation stability. SS 347H maintains its structural integrity even under continuous heat exposure and thermal cycling, while its austenitic structure ensures good toughness and reliable weldability. These mechanical properties make 347H Fasteners perfect for high-stress, high-temperature assemblies that demand long-lasting performance and resistance to intergranular corrosion.
