These washers are primarily made of iron, containing 12–14% chromium and a significant amount of carbon (at least 0.15%), which allows them to be heat-treated for enhanced hardness. After treatment, they can achieve tensile strengths between 700–900 MPa and hardness levels up to 50 HRC. While they may not resist corrosion as well as austenitic grades, they perform admirably in dry or mildly corrosive settings. Their key features include excellent wear resistance, strength, and stability under mechanical stress and vibration.
