The Stainless Steel 440C Fasteners are created from high-carbon martensitic stainless steel, which contains about 16–18% chromium and 0.95–1.20% carbon. This specific composition allows the material to achieve remarkable hardness and strength after heat treatment. Their mechanical properties include high tensile and yield strength, excellent wear and abrasion resistance, good fatigue strength, and dimensional stability. While they offer moderate corrosion resistance, they also maintain their mechanical integrity under heavy loads and repeated stress.
