A high-temperature austenitic stainless steel alloy with 24–26% chromium and 19–22% nickel is used to make Stainless Steel 310H Nuts, which provide remarkable resistance to corrosion, scaling, and oxidation at high temperatures. The high carbon content of the alloy improves mechanical stability and creep resistance when exposed to high temperatures for an extended period of time. These nuts are suitable for harsh industrial conditions because of their exceptional hardness and ductility, as well as their tensile strength of up to 515 MPa and yield strength of about 205 MPa. Long service life, little deformation, and exceptional performance in extreme heat conditions are guaranteed by their sturdy structure.
