Stainless Steel 420 is a high-carbon martensitic stainless steel that contains about 12–14% chromium and low carbon content, allowing it to be heat treated for increased hardness. Mechanically, it boasts impressive tensile and yield strength, high hardness, and good wear resistance. This alloy offers moderate corrosion resistance while still maintaining toughness, making it suitable for parts that face mechanical stress and moderate corrosive environments. Its unique combination of hardness, strength, and durability ensures long-lasting reliability in industrial and precision engineering applications.
