Stainless Steel 420 is a high-carbon martensitic stainless steel alloy that contains around 12–14% chromium and at least 0.15% carbon. It boasts good corrosion resistance, impressive hardness, and high tensile strength when heat-treated. Typical mechanical properties include tensile strength ranging from 700–1000 MPa, yield strength of about 500 MPa, and hardness levels reaching 50–55 HRC. SS 420 is magnetic and can achieve a bright polish. While it may not resist corrosion as well as austenitic grades, it excels in dry or mildly corrosive settings where strength and edge retention are crucial.
