Home > Stud Bolts > Stainless Steel 347H Stud Bolts
Stainless Steel 347H Stud Bolts are top-notch fastening components crafted for situations that demand outstanding corrosion resistance, high-temperature strength, and lasting durability. This stabilized austenitic stainless steel features niobium, which helps prevent intergranular corrosion, ensuring dependable performance in boilers, heat exchangers, pressure vessels, and various high-temperature industrial equipment.
These stud bolts are mainly made up of iron, chromium, nickel, and niobium. Chromium offers corrosion resistance, while nickel boosts toughness and ductility. Niobium plays a crucial role in stabilizing the microstructure, helping to maintain mechanical integrity even at elevated temperatures. With excellent tensile strength, creep resistance, and thermal stability, these stud bolts are perfect for critical applications in tough, high-temperature environments.
