When it comes to composition, these Hastelloy Screws are primarily made up of nickel (57–63%), molybdenum (16–17%), iron (5–7%), and chromium (4–7%), with a touch of cobalt and tungsten depending on the specific grade. This unique mix gives them remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking, whether in oxidizing or reducing environments. They also boast impressive mechanical properties, with tensile strength ranging from 480–690 MPa and yield strength between 205–310 MPa, along with high toughness, ductility, and fatigue resistance. This means you can count on them to perform reliably, even under extreme temperature and pressure conditions.
