High Hardness and Wear Resistance-Best Steel for Forging Dies

2. PM23 Powder High-Speed Steel

PM23 is a type of Pulvermetallurgie (PM) Stahl.

• Härte: HRC64–66

• Steel purity is high, Also knacken is reduced.

• Strong wear resistance and toughness are achieved.

• Commonly used in fine stamping dies.

• Jedoch, the price is higher.

3. SKH-9 and DC53 Steel

When die life matters:

• SKH-9 high-speed steel can be selected.

  • Härte: HRC62–64

  • High tungsten content improves wear resistance.

• If cost is a concern:

  • DC53 steel is an option.

  • Härte: HRC60–63

  • Better wear and corner resistance than Cr12MoV.

4. Tungsten Steel (Hard Alloy)

Tungsten steel is known for its extreme Härte Und hohe Verschleißfestigkeit.

• It stays hard even at 500°C.

• At 1000°C, it still keeps high hardness.

• Also offers strength, Zähigkeit, und Korrosionsbeständigkeit.

5. CPM-20CV Steel

CPM-20CV is a powder tool steel.

• Excellent wear and edge retention

• High corrosion resistance due to chromium

• Useful ratings:

  • Edge Retention: 8

  • Korrosionsbeständigkeit: 6

  • Grindability: 5

  • Popularity: 4

2. Cr12MoV Steel

This steel is widely used in cold dies.

• Excellent wear resistance

• Maintains cutting performance at high temperatures

3. Edelstahl

Stainless steel contains chromium and nickel.

• Offers corrosion and wear resistance

• Keeps surface finish and mold quality

• Also has high hardness, which increases die life

4. Cr12 Steel

Cr12 is a cold work die steel mit:

• High carbon and chromium levels

• Very high hardness after heat treatment

• Used for bending dies, punching dies, and cutting tools

5. P20 and S136 Steel

• P20 Steel (2311 Stahl):

  • Vorgehärtet

  • Good processing and wear performance

  • Used for mid-size plastic mold parts

• S136 Steel (4Cr13MoV):

  • High-grade stainless

  • Offers good corrosion resistance

  • Ideal for precision molds
