Hastelloy Nuts are primarily composed of nickel, molybdenum, and chromium, with small additions of iron, cobalt, and tungsten to enhance corrosion resistance and strength. These nuts exhibit excellent tensile strength, typically ranging from 690 to 785 MPa, and superior yield strength, making them ideal for high-stress applications. They maintain excellent mechanical stability and oxidation resistance even at elevated temperatures. Hastelloy Nuts also demonstrate outstanding resistance to pitting, crevice corrosion, and stress cracking, ensuring long-term performance in aggressive chemical and oxidizing environments.
