These fasteners are crafted from martensitic stainless steel, which contains about 11–13% chromium along with controlled amounts of carbon and other alloying elements. This specific composition allows for heat treatment that results in high tensile strength, good yield strength, and increased hardness. They boast mechanical properties like excellent fatigue resistance, moderate ductility, and dependable performance under both thermal and mechanical stress. Notably, they maintain their strength even at elevated temperatures and provide better oxidation resistance compared to many standard martensitic stainless steels.
