Hastelloy Screws are primarily composed of nickel, molybdenum, and chromium, with trace elements such as iron, cobalt, and tungsten to enhance corrosion resistance and mechanical performance. These screws exhibit excellent tensile strength, typically around 690 MPa, and maintain their structural integrity under high-stress and high-temperature conditions. They also provide superior resistance to pitting, crevice corrosion, and stress cracking in both oxidizing and reducing environments. The combination of toughness and durability makes Hastelloy Screws ideal for demanding industrial use.
