Stainless Steel 440B is a high-carbon martensitic stainless steel that contains around 17% Chromium, 1% Manganese, 1% Molybdenum, and 0.9–1.2% Carbon. It boasts excellent hardness and strength after heat treatment. SS 440B bolts can achieve a tensile strength of up to 760 MPa and hardness levels reaching 58 HRC, along with moderate corrosion resistance. These mechanical properties make it perfect for cutting tools, heavy-duty applications, and settings that demand superior wear resistance. While it may not be as corrosion-resistant as austenitic grades, it offers remarkable toughness in dry and mildly corrosive environments when properly treated.
