4140 Steel vs 1.2311 Steel: Which is Best for Your Application?

Both 4140 alloy steel and 1.2311 mold steel are very versatile materials with different properties and applications. Choosing the best material for your application depends on a number of factors, such as the type of application, the characteristics required, and the production process involved.

  • 4140 alloy steel is a low alloy steel containing chromium, molybdenum and manganese. It has excellent strength, toughness and fatigue resistance. It is commonly used in the manufacture of gears, axles, shafts, etc.
  • 1.2311 mold steel, also known as P20 steel, is a prehardened tool steel containing chromium, molybdenum, and carbon. It has excellent machinability, dimensional stability and good toughness. It is often used to manufacture injection molds, die casting molds and other precision tools.

4140 alloy steel is generally considered superior to 1.2311 mold steel in strength and toughness. However, if your application requires excellent machinability, dimensional stability, and good toughness, then 1.2311 die steel may be a better choice.

The choice of 4140 alloy steel or 1.2311 die steel will depend on your specific application requirements. It is recommended that you consult a materials specialist to help you make the best choice for your application. (4140 Steel vs 1.2311 Steel)
