What Is 420 Stainless Steel?


420 stainless steel is a type of martensitic stainless steel that belongs to the 400 series of stainless steel. Martensitic stainless steels are known for their high strength, hardness, and corrosion resistance, primarily achieved through heat treatment. The number “420” indicates the specific composition of this stainless steel, with 4% being the minimum percentage of chromium and 20% being the maximum percentage of carbon in its alloy.

Key Features of 420 Stainless Steel


  1. Hardness: 420 stainless steel is known for its high hardness, achieved through heat treatment processes like quenching and tempering.
  2. Corrosion Resistance: Offers good corrosion resistance, particularly in hardened and tempered conditions, although not as corrosion-resistant as austenitic stainless steel.
  3. Wear Resistance: Exhibits excellent wear resistance due to its high hardness, making it suitable for applications like cutting tools and industrial components.
  4. Magnetic Properties: Possesses magnetic properties in all conditions, which can be advantageous in certain applications.
  5. Carbon Content: Contains a significant percentage of carbon (0.15 – 0.40%), contributing to its strength and hardness.
  6. Chromium Content: Contains chromium (12.00 – 14.00%) for corrosion resistance and improved hardenability.
  7. Machinability: The inclusion of manganese and silicon in limited amounts enhances machinability.
  8. Heat Treatment: Can be heat-treated to achieve different mechanical properties, allowing for customization based on application requirements.
  9. Phosphorus and Sulfur Content: Maintains low levels of phosphorus (0.040% max) and sulfur (0.030% max) to ensure good weldability and avoid adverse effects on properties.
