**Incoloy Stud Bolts** mainly comprise nickel (30–46%), chromium (19–23%), and iron (the balance), with small amounts of molybdenum, copper, and titanium added based on the specific grade (like Incoloy 800, 825, or 925). These stud bolts boast a tensile strength ranging from 550 to 750 MPa and a yield strength between 250 and 450 MPa. **Incoloy** is known for its excellent resistance to oxidation, scaling, and stress-corrosion cracking at high temperatures, along with good ductility, weldability, and fatigue resistance, making it ideal for demanding industrial applications.
