Khaled Stainless, based in Cairo, Egypt, is a trusted manufacturer and supplier of Stainless Steel 347H Nuts, specifically crafted for high-temperature and high-pressure fastening needs. Using top-notch raw materials and precise machining techniques, these nuts ensure outstanding dimensional accuracy, strength, and durability over time. Khaled Stainless provides SS 347H nuts that meet ASTM and international standards, catering to industries that demand fasteners capable of withstanding mechanical stress and resisting corrosion, even in extreme temperatures and challenging service conditions.
Stainless Steel 347H is a high-carbon, niobium-stabilized austenitic stainless steel. The niobium helps prevent carbide precipitation and boosts resistance to intergranular corrosion at high temperatures. SS 347H nuts are known for their impressive tensile strength, excellent creep resistance, and remarkable toughness. This alloy maintains its mechanical stability and oxidation resistance even at elevated temperatures. Plus, it offers good weldability and durability, making it a great choice for demanding thermal and pressure applications.
