Hastelloy Screws are primarily crafted from nickel-based alloys, including Hastelloy C-276 and C-22, which incorporate elements like molybdenum, chromium, iron, cobalt, and tungsten. These alloys are known for their outstanding resistance to pitting, stress corrosion cracking, and powerful oxidizers like nitric acid. Typically, Hastelloy Screws boast a tensile strength ranging from 690 to 785 MPa, maintaining their mechanical integrity even in high-temperature and highly corrosive settings. Their remarkable weldability, ductility, and durability make them ideal for extreme operating conditions where standard stainless steel or other alloys might not hold up.
