Stainless Steel 440C Nuts are crafted from a high-carbon martensitic stainless steel alloy, which includes Carbon (0.95–1.20%), Chromium (16–18%), and trace amounts of Manganese, Silicon, and other elements. When heat-treated, 440C can reach Rockwell hardness levels of up to 60 HRC, making it the hardest stainless steel grade commonly available. It boasts impressive tensile strength, wear resistance, and moderate corrosion resistance in less severe environments. These mechanical properties make 440C nuts perfect for precision mechanical assemblies where long-lasting reliability, stability, and strength are essential, whether under static or dynamic loads.
