These Stainless Steel 347H Nuts are made from an austenitic stainless steel alloy that’s stabilized with niobium (columbium) and features a higher carbon content than SS 347, which boosts their high-temperature strength. Their composition includes chromium, nickel, carbon, manganese, silicon, sulfur, phosphorus, and trace elements. These nuts are known for their high tensile strength, excellent creep resistance, and remarkable stress rupture properties. They maintain mechanical stability even in continuous service at elevated temperatures of up to 900°C and offer exceptional resistance to intergranular corrosion. SS 347H Nuts also showcase great oxidation resistance along with good weldability and formability, making them ideal for heavy-duty, high-temperature applications.
