What Is D7 Tool Steel?

D7 steel is a high-carbon, high-chromium tool steel known for its high wear resistance, toughness, and excellent dimensional stability. It has a relatively low distortion during heat treatment and can be easily machined. The high chromium content provides corrosion resistance and improves the wear resistance of the steel. The high carbon content also contributes to its hardness and wear resistance.

D7 steel can be heat treated to achieve a range of hardness levels, which makes it versatile for a variety of industrial applications. It is typically supplied in the annealed condition, which allows for easier machining, and then heat treated to achieve the desired hardness.

D7 steel is a versatile tool steel that is commonly used in a range of industrial applications that require high wear resistance and toughness. Some of the typical applications of D7 steel include:

  • Stamping dies: D7 steel is often used to make stamping dies for metalworking applications. Its high wear resistance and toughness make it well-suited for this purpose.
  • Thread rolling dies: D7 steel is also commonly used to make thread rolling dies. Its hardness and wear resistance make it ideal for this application.
  • Cutting tools: D7 steel can be used to make a variety of cutting tools, such as shears, knives, and blades. Its high hardness and toughness make it well-suited for these applications.
  • Cold work tooling: D7 steel is often used in cold work tooling applications, such as forming, bending, and blanking. Its high dimensional stability and low distortion during heat treatment make it well-suited for these applications.
  • Plastic molding: D7 steel is also used in plastic molding applications. Its high wear resistance and toughness make it suitable for making molds for plastic parts.
