Stainless Steel 420 Nuts are martensitic stainless steel fasteners that contain trace amounts of silicon and manganese, as well as 12–14% chromium and 0.15–0.40% carbon. With tensile strengths between 700 and 800 MPa and hardness levels up to 50 HRC, their chemical makeup enables them to be heat-treated for high hardness and wear resistance. These nuts have a moderate level of corrosion resistance and mechanical strength. They are perfect for settings where durability and edge retention are essential because of their capacity to preserve structural integrity under mechanical stress.
