Stainless Steel 420 is a high-carbon martensitic stainless steel containing chromium as its main alloying element. It offers excellent hardness, impressive tensile strength, and good corrosion resistance in mild environments when properly heat-treated. This alloy can achieve high levels of hardness through quenching and tempering, making it ideal for applications requiring superior wear resistance. SS 420 also provides moderate ductility and good edge retention. Its mechanical performance, especially after heat treatment, makes it suitable for demanding uses where strength, durability, and precision are essential.
