This unique composition bestows on the fasteners better resistance to intergranular corrosion—a very vital property for its integrity in high-temperature environments. The high content of chrome in this alloy provides it, together with niobium and tantalum, with a very good resistance to oxidation, allowing long service even under very aggressive conditions. Our Stainless Steel 347H Fasteners do have high mechanical strength, with good tensile and yield strengths, in addition to excellent weldability. With these features, they turn out to be suitable for various principal applications spread across different industries.

Stainless Steel 347H Fasteners find broad usage in the petrochemical industry for equipment and components running with corrosive chemicals and high-temperature gases, particularly as noticed in pipelines, valves, and fittings. Their heat resistance or resistance makes them quite serviceable in chemical treatment plants by handling corrosive acids, akalis, and numerous other caustic substances. In the production of energy, specifically from atomic and thermal fossil fuel power plants, the output is also used for Stainless Steel 347H Fasteners subjected to such very high temperatures and aggressive conditions. These fasteners are also of extreme importance in aerospace applications because of the need for high strength and resistance to thermal stress to ensure the reliability and safety of aerospace components.
